.30-06 Springfield
–
The.30 refers to the caliber of the bullet, and the 06 refers to the year the cartridge was adopted—1906. It replaced the. 30-03, 6mm Lee Navy, and. 30-40 Krag cartridges and it remains a very popular sporting round, with ammunition produced by all major manufacturers. In the early 1890s, the U. S. military adopted the smokeless powder. 30-40 Krag rimmed cartridge, the 1894 version of that cartridge used a 220-grain round-nose bullet. Around 1901, the U. S. started developing an experimental rimless cartridge for a Mauser action with box magazine and that led to the 1903. 30-03 rimless service round that used the same 220-grain round-nose bullet as the Krag. The. 30-03 achieved a velocity of 2,300 ft/s. Consequently, the round-nosed U. S. 30-03 service cartridge was falling behind. For these reasons, the U. S. military developed a new, lighter, cartridge in 1906, the cartridge was loaded with Military Rifle 21 propellant, and its maximum range was claimed to be 4,700 yd. The M1903 Springfield rifle, which had been introduced alongside the. 30-03 cartridge, was modified to accept the new. 30-06 Springfield cartridge. Modifications to the rifle included shortening the barrel at its breech and resizing the chamber, other changes to the rifle included elimination of the troublesome rod bayonet of the earlier Springfield rifles. The M1906 maximum range was originally overstated, when the M1906 cartridge was developed, the range tests had been done to only 1,800 yards, distances beyond that were estimated, but the estimate for extreme range was wrong by almost 40 percent. The range discrepancy became evident during World War I, before the widespread employment of light mortars and artillery, long-range machine gun barrage or indirect fires were considered important in U. S. infantry tactics. When the US entered World War I, it did not have machine guns, so it acquired British. When those weapons were replaced with US machine guns firing the M1906 round. Firing tests performed around 1918 at Borden Brook Reservoir, Miami, patrone was inroduced in 1914 and used a 197. 5-grain s. S. - schweres Spitzgeschoß boat-tail bullet which had a maximum range of approximately 5,140 yd. Its maximum range was approximately 5,500 yd. Additionally, wartime surplus totaled over 2 billion rounds of ammunition. Army regulations called for training use of the oldest ammunition first, as a result, the older. 30-06 ammunition was expended for training, stocks of.30 M1 Ball ammunition were allowed to slowly grow until all of the older M1906 ammunition had been fired. By 1936, it was discovered that the range of the.30 M1 Ball ammunition with its boat-tailed spitzer bullets was beyond the safety limitations of many ranges. An emergency order was made to manufacture quantities of ammunition that matched the ballistics of the earlier M1906 cartridge as soon as possible

Soft-point bullet
–
A soft-point bullet, also known as a soft-nosed bullet, is a jacketed expanding bullet with a soft metal core enclosed by a stronger metal jacket left open at the forward tip. A soft-point bullet is intended to expand upon striking flesh to cause a wound diameter greater than the bullet diameter, jacketed soft point is usually abbreviated JSP in the ammunition and reloading industry. Lead-alloy bullets used with gunpowder firearms were unsatisfactory at the bullet velocities available from rifles loaded with nitrocellulose propellants like cordite. The lead-alloy core was swaged into a cup of the metal covering the front and sides of the core. The bullet jacket may be described as an envelope, steel envelope, or hard envelope. Reversing the direction of jacket placement leaves the exposed core on the forward tip of the bullet creating a soft-point bullet. Soft-point bullets expose the soft lead-alloy core on the part of the bullet most likely to be deformed when striking a target. The sides of the bullet remain covered by the jacket to reliably impart stabilizing rotation from rifling, a core of pure lead is softer than a core of lead alloyed with metals like antimony and tin. Some jacket alloys have greater strength than others, and, for any given alloy and annealing process. Energy available to expand the bullet is proportional to the square of the velocity at which the bullet strikes the target, if the bullet passes through the target, the energy represented by the square of the velocity of the departing bullet has no effect on the target. Soft point bullets may not expand if they strike a target at low velocity, varmint rifle bullets with thin jackets are intended to expand rapidly and disintegrate upon encountering minimum resistance. Bullets intended for hunting are designed to increase their forward diameter while remaining intact to penetrate deeply enough to damage internal organs likely to cause rapid death. Big-game bullets sometimes have a specialized jacket including a center baffle between a forward core intended to expand and another core intended to remain intact. Alternative designs include a jacket with a thicker belt around the central part of the bullet intended to resist expansion while the thinner forward part of the bullet jacket ruptures. Some bullets have a formed from a soft alloy in the forward part of the bullet bonded to a harder alloy core in the rear of the bullet. Others have a jacket which is thicker near the base of the bullet, soft-point bullets are similar to jacketed hollow-point bullets, because both have a jacket open on the forward tip. Bullets with an amount of core exposed forward of the jacket might have a hollow point within that core. Jacketed flat point may describe either soft-point or full metal jacket bullets with a flat, until recently, flat-point bullets were required in centerfire rifles with tubular magazines, such as the Winchester rifle, where the rounds are stored front-to-back

Rifle
–
A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves cut into the barrel walls. The raised areas of the rifling are called lands, which contact with the projectile. When the projectile leaves the barrel, this spin lends gyroscopic stability to the projectile and prevents tumbling and this allows the use of aerodynamically-efficient bullets and thus improves range and accuracy. The word rifle originally referred to the grooving, and a rifle was called a rifled gun, the word rifle is now used for any long hand-held aimed device activated by a trigger, such as Air rifles and the Personnel halting and stimulation response rifle. Rifles are used in warfare, hunting and shooting sports, formerly, rifles only fired a single projectile with each squeeze of the trigger. Modern rifles are capable of firing more than one round per trigger squeeze, some fire in an automatic mode. Thus, modern automatic rifles overlap to some extent in design, in fact, many light machine guns are adaptations of existing automatic rifle designs. A militarys light machine guns are chambered for the same caliber ammunition as its service rifles. Generally, the difference between a rifle and a machine gun comes down to weight, cooling system. Modern military rifles are fed by magazines, while machine guns are generally belt-fed, many machine guns allow the operator to quickly exchange barrels in order to prevent overheating, whereas rifles generally do not. Most machine guns fire from a bolt in order to reduce the danger of cook-off. Machine guns are often crewed by more than one soldier, the rifle is an individual weapon, the term rifle is sometimes used to describe larger crew-served rifled weapons firing explosive shells, for example, recoilless rifles. In many works of fiction a rifle refers to any weapon that has a stock and is shouldered before firing, the origins of rifling are difficult to trace, but some of the earliest practical experiments seem to have occurred in Europe during the 15th century. Archers had long realized that a twist added to the feathers of their arrows gave them greater accuracy. This might also have led to a increase in accuracy. Rifles were created as an improvement in the accuracy of smooth bore muskets, the black powder used in early muzzle-loading rifles quickly fouled the barrel, making loading slower and more difficult. Since musketeers could not afford to take the time to stop and clean their barrels in the middle of a battle, rifles were limited to use by sharpshooters, muskets were smoothbore, large caliber weapons using ball-shaped ammunition fired at relatively low velocity. Due to the high cost and great difficulty of manufacturing, and the need to load readily from the muzzle

United Kingdom of Great Britain and Ireland
–
The United Kingdom of Great Britain and Ireland was established as a sovereign state on 1 January 1801 by the Acts of Union 1800, which merged the kingdoms of Great Britain and Ireland. The growing desire for an Irish Republic led to the Irish War of Independence, Northern Ireland remained part of the United Kingdom, and the state was consequently renamed the United Kingdom of Great Britain and Northern Ireland. Britain financed the European coalition that defeated France in 1815 in the Napoleonic Wars, the British Empire thereby became the foremost world power for the next century. The Crimean War with Russia and the Boer wars were relatively small operations in a largely peaceful century, rapid industrialisation that began in the decades prior to the states formation continued up until the mid-19th century. A devastating famine, exacerbated by government inaction in the century, led to demographic collapse in much of Ireland. It was an era of economic modernization and growth of industry, trade and finance. Outward migration was heavy to the colonies and to the United States. Britain also built up a large British Empire in Africa and Asia, India, by far the most important possession, saw a short-lived revolt in 1857. In foreign policy Britain favoured free trade, which enabled its financiers and merchants to operate successfully in many otherwise independent countries, as in South America. Britain formed no permanent military alliances until the early 20th century, when it began to cooperate with Japan, France and Russia, and moved closer to the United States. A brief period of limited independence for Ireland came to an end following the Irish Rebellion of 1798, the British governments fear of an independent Ireland siding against them with the French resulted in the decision to unite the two countries. This was brought about by legislation in the parliaments of both kingdoms and came into effect on 1 January 1801, however, King George III was bitterly opposed to any such Emancipation and succeeded in defeating his governments attempts to introduce it. When the Treaty of Amiens ended the war, Britain agreed to return most of the territories it had seized, in May 1803, war was declared again. In 1806, Napoleon issued the series of Berlin Decrees, which brought into effect the Continental System and this policy aimed to eliminate the threat from the British by closing French-controlled territory to foreign trade. Frances population and agricultural capacity far outstripped that of the British Isles, Napoleon expected that cutting Britain off from the European mainland would end its economic hegemony. The Spanish uprising in 1808 at last permitted Britain to gain a foothold on the Continent, after Napoleons surrender and exile to the island of Elba, peace appeared to have returned. The Allies united and the armies of Wellington and Blucher defeated Napoleon once, simultaneous with the Napoleonic Wars, trade disputes, arming hostile Indians and British impressment of American sailors led to the War of 1812 with the United States. The war was little noticed in Britain, which could devote few resources to the conflict until the fall of Napoleon in 1814, American frigates inflicted a series of defeats on the Royal Navy, which was short on manpower due to the conflict in Europe

United Kingdom
–
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, the United Kingdom includes the island of Great Britain, Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state—the Republic of Ireland. The Irish Sea lies between Great Britain and Ireland, with an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants, together, this makes it the fourth-most densely populated country in the European Union. The United Kingdom is a monarchy with a parliamentary system of governance. The monarch is Queen Elizabeth II, who has reigned since 6 February 1952, other major urban areas in the United Kingdom include the regions of Birmingham, Leeds, Glasgow, Liverpool and Manchester. The United Kingdom consists of four countries—England, Scotland, Wales, the last three have devolved administrations, each with varying powers, based in their capitals, Edinburgh, Cardiff and Belfast, respectively. The relationships among the countries of the UK have changed over time, Wales was annexed by the Kingdom of England under the Laws in Wales Acts 1535 and 1542. A treaty between England and Scotland resulted in 1707 in a unified Kingdom of Great Britain, which merged in 1801 with the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland. Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain, there are fourteen British Overseas Territories. These are the remnants of the British Empire which, at its height in the 1920s, British influence can be observed in the language, culture and legal systems of many of its former colonies. The United Kingdom is a country and has the worlds fifth-largest economy by nominal GDP. The UK is considered to have an economy and is categorised as very high in the Human Development Index. It was the worlds first industrialised country and the worlds foremost power during the 19th, the UK remains a great power with considerable economic, cultural, military, scientific and political influence internationally. It is a nuclear weapons state and its military expenditure ranks fourth or fifth in the world. The UK has been a permanent member of the United Nations Security Council since its first session in 1946 and it has been a leading member state of the EU and its predecessor, the European Economic Community, since 1973. However, on 23 June 2016, a referendum on the UKs membership of the EU resulted in a decision to leave. The Acts of Union 1800 united the Kingdom of Great Britain, Scotland, Wales and Northern Ireland have devolved self-government

Second Boer War
–
The Second Boer War, usually known as the Boer War and also at the time as the South African War, started on 11 October 1899 and ended on 31 May 1902. Great Britain defeated two Boer states in South Africa, the South African Republic and the Orange Free State, Britain was aided by its Cape Colony, Colony of Natal and some native African allies. The British war effort was supported by volunteers from the British Empire, including Southern Africa, the Australian colonies, Canada, India. All other nations were neutral, but public opinion in them was largely hostile to Britain, inside Britain and its Empire there also was significant opposition to the Second Boer War. The British were overconfident and under-prepared, the Boers were very well armed and struck first, besieging Ladysmith, Kimberley, and Mafeking in early 1900, and winning important battles at Colenso, Magersfontein and Stormberg. Staggered, the British brought in numbers of soldiers and fought back. General Redvers Buller was replaced by Lord Roberts and Lord Kitchener and they relieved the three besieged cities, and invaded the two Boer republics in late 1900. The onward marches of the British Army were so overwhelming that the Boers did not fight staged battles in defense of their homeland, the British quickly seized control of all of the Orange Free State and Transvaal, as the civilian leadership went into hiding or exile. In conventional terms, the war was over, Britain officially annexed the two countries in 1900, and called a khaki election to give the government another six years of power in London. However, the Boers refused to surrender and they reverted to guerrilla warfare under new generals Louis Botha, Jan Smuts, Christiaan de Wet and Koos de la Rey. Two more years of attacks and quick escapes followed. As guerrillas without uniforms, the Boer fighters easily blended into the farmlands, which provided hiding places, supplies, the British solution was to set up complex nets of block houses, strong points, and barbed wire fences, partitioning off the entire conquered territory. The civilian farmers were relocated into concentration camps, where very large proportions died of disease, especially the children, then the British mounted infantry units systematically tracked down the highly mobile Boer guerrilla units. The battles at this stage were small operations with few combat casualties The war ended in surrender, the British successfully won over the Boer leaders, who now gave full support to the new political system. Both former republics were incorporated into the Union of South Africa in 1910, the conflict is commonly referred to as simply the Boer War, since the First Boer War is much less well known. Boer was the term for Afrikaans-speaking white South Africans descended from the Dutch East India Companys original settlers at the Cape of Good Hope. It is officially called the South African War and it is known as the Anglo-Boer War among some South Africans. In Afrikaans it may be called the Anglo-Boereoorlog, Tweede Boereoorlog, in South Africa it is officially called the South African War

Boxer Rebellion
–
The Boxer Rebellion, Boxer Uprising or Yihequan Movement a violent anti-foreign and anti-Christian uprising that took place in China between 1899 and 1901, towards the end of the Qing dynasty. The uprising took place against a background of severe drought and the disruption caused by the growth of foreign spheres of influence, Foreigners and Chinese Christians sought refuge in the Legation Quarter. Diplomats, foreign civilians and soldiers as well as Chinese Christians in the Legation Quarter were placed under siege by the Imperial Army of China, Chinese officialdom was split between those supporting the Boxers and those favoring conciliation, led by Prince Qing. The supreme commander of the Chinese forces, the Manchu General Ronglu, the Eight-Nation Alliance, after being initially turned back, brought 20,000 armed troops to China, defeated the Imperial Army, and captured Beijing on August 14, lifting the siege of the Legations. Uncontrolled plunder of the capital and the surrounding countryside ensued, along with the execution of those suspected of being Boxers. The Empress Dowager then sponsored a set of institutional and fiscal changes in an attempt to save the dynasty by reforming it. The Righteous and Harmonious Fists arose in the sections of the northern coastal province of Shandong long known for social unrest, religious sects. American Christian missionaries were probably the first to refer to the well-trained, athletic men as Boxers, because of the martial arts. Their primary practice was a type of possession which involved the whirling of swords, violent prostrations. The opportunities to fight back Western encroachment and colonization were especially attractive to unemployed village men, the tradition of possession and invulnerability went back several hundred years but took on special meaning against the powerful new weapons of the West. The Boxers, armed with rifles and swords, claimed supernatural invulnerability towards blows of cannon, rifle shots, furthermore, the Boxer groups popularly claimed that millions of soldiers of Heaven would descend to assist them in purifying China of foreign oppression. The Big Swords, emboldened by this support, also attacked their local Catholic village rivals. The Big Swords responded by attacking Catholic churches and burning them, the line between Christians and bandits, remarks one recent historian, became increasingly indistinct. As a result of pressure in the capital, Yuxian executed several Big Sword leaders. More martial secret societies started emerging after this, the early years saw a variety of village activities, not a broad movement or a united purpose. Martial folk religious societies such as the Baguadao prepared the way for the Boxers, like the Red Boxing school or the Plum Flower Boxers, the Boxers of Shandong were more concerned with traditional social and moral values, such as filial piety, than with foreign influences. One leader, for instance, Zhu Hongdeng, started as a healer, specializing in skin ulcers. Zhu claimed descent from Ming dynasty emperors, since his surname was the surname of the Ming imperial family and he announced that his goal was to Revive the Qing and destroy the foreigners

World War I
–
World War I, also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history and it was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. The war drew in all the worlds great powers, assembled in two opposing alliances, the Allies versus the Central Powers of Germany and Austria-Hungary. These alliances were reorganised and expanded as more nations entered the war, Italy, Japan, the trigger for the war was the assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo on 28 June 1914. This set off a crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia. Within weeks, the powers were at war and the conflict soon spread around the world. On 25 July Russia began mobilisation and on 28 July, the Austro-Hungarians declared war on Serbia, Germany presented an ultimatum to Russia to demobilise, and when this was refused, declared war on Russia on 1 August. Germany then invaded neutral Belgium and Luxembourg before moving towards France, after the German march on Paris was halted, what became known as the Western Front settled into a battle of attrition, with a trench line that changed little until 1917. On the Eastern Front, the Russian army was successful against the Austro-Hungarians, in November 1914, the Ottoman Empire joined the Central Powers, opening fronts in the Caucasus, Mesopotamia and the Sinai. In 1915, Italy joined the Allies and Bulgaria joined the Central Powers, Romania joined the Allies in 1916, after a stunning German offensive along the Western Front in the spring of 1918, the Allies rallied and drove back the Germans in a series of successful offensives. By the end of the war or soon after, the German Empire, Russian Empire, Austro-Hungarian Empire, national borders were redrawn, with several independent nations restored or created, and Germanys colonies were parceled out among the victors. During the Paris Peace Conference of 1919, the Big Four imposed their terms in a series of treaties, the League of Nations was formed with the aim of preventing any repetition of such a conflict. This effort failed, and economic depression, renewed nationalism, weakened successor states, and feelings of humiliation eventually contributed to World War II. From the time of its start until the approach of World War II, at the time, it was also sometimes called the war to end war or the war to end all wars due to its then-unparalleled scale and devastation. In Canada, Macleans magazine in October 1914 wrote, Some wars name themselves, during the interwar period, the war was most often called the World War and the Great War in English-speaking countries. Will become the first world war in the sense of the word. These began in 1815, with the Holy Alliance between Prussia, Russia, and Austria, when Germany was united in 1871, Prussia became part of the new German nation. Soon after, in October 1873, German Chancellor Otto von Bismarck negotiated the League of the Three Emperors between the monarchs of Austria-Hungary, Russia and Germany

British Empire
–
The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom and its predecessor states. It originated with the possessions and trading posts established by England between the late 16th and early 18th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, 23% of the population at the time. As a result, its political, legal, linguistic and cultural legacy is widespread, during the Age of Discovery in the 15th and 16th centuries, Portugal and Spain pioneered European exploration of the globe, and in the process established large overseas empires. Envious of the great wealth these empires generated, England, France, the independence of the Thirteen Colonies in North America in 1783 after the American War of Independence caused Britain to lose some of its oldest and most populous colonies. British attention soon turned towards Asia, Africa, and the Pacific, after the defeat of France in the Revolutionary and Napoleonic Wars, Britain emerged as the principal naval and imperial power of the 19th century. In the early 19th century, the Industrial Revolution began to transform Britain, the British Empire expanded to include India, large parts of Africa and many other territories throughout the world. In Britain, political attitudes favoured free trade and laissez-faire policies, during the 19th Century, Britains population increased at a dramatic rate, accompanied by rapid urbanisation, which caused significant social and economic stresses. To seek new markets and sources of raw materials, the Conservative Party under Benjamin Disraeli launched a period of imperialist expansion in Egypt, South Africa, Canada, Australia, and New Zealand became self-governing dominions. By the start of the 20th century, Germany and the United States had begun to challenge Britains economic lead, subsequent military and economic tensions between Britain and Germany were major causes of the First World War, during which Britain relied heavily upon its empire. The conflict placed enormous strain on the military, financial and manpower resources of Britain, although the British Empire achieved its largest territorial extent immediately after World War I, Britain was no longer the worlds pre-eminent industrial or military power. In the Second World War, Britains colonies in Southeast Asia were occupied by Imperial Japan, despite the final victory of Britain and its allies, the damage to British prestige helped to accelerate the decline of the empire. India, Britains most valuable and populous possession, achieved independence as part of a larger movement in which Britain granted independence to most territories of the empire. The transfer of Hong Kong to China in 1997 marked for many the end of the British Empire, fourteen overseas territories remain under British sovereignty. After independence, many former British colonies joined the Commonwealth of Nations, the United Kingdom is now one of 16 Commonwealth nations, a grouping known informally as the Commonwealth realms, that share a monarch, Queen Elizabeth II. The foundations of the British Empire were laid when England and Scotland were separate kingdoms. In 1496, King Henry VII of England, following the successes of Spain and Portugal in overseas exploration, Cabot led another voyage to the Americas the following year but nothing was ever heard of his ships again

Irish War of Independence
–
The Irish War of Independence or Anglo-Irish War or the Tan War was a guerrilla war fought from 1919 to 1921 between the Irish Republican Army and the British security forces in Ireland. It was an escalation of the Irish revolutionary period into armed conflict, in the December 1918 election, the Irish republican party Sinn Féin won a landslide victory in Ireland. On 21 January 1919 they formed a government and declared independence from Britain. Later that day, two members of the British-organized armed police force, the Royal Irish Constabulary, were dead in County Tipperary by IRA members acting on their own initiative. This is often seen as the beginning of the conflict, for much of 1919, IRA activity primarily involved capturing weapons and freeing republican prisoners. In September that year the British government outlawed the Dáil and Sinn Féin, the IRA began ambushing RIC and British Army patrols, attacking their barracks and forcing isolated barracks to be abandoned. The British government bolstered the RIC with recruits from Britain—the Black and Tans and Auxiliaries—who became notorious for ill-discipline, the conflict as a result is often referred to as the Black and Tan War or simply the Tan War. While around 300 people had killed in the conflict up to late 1920. A week later, seventeen Auxiliaries were killed by the IRA in an ambush at Kilmichael in County Cork, the British government declared martial law in much of southern Ireland. The centre of Cork City was burnt out by British forces in December 1920, violence continued to escalate over the next seven months, when 1,000 people were killed and 4,500 republicans were interned. The fighting was concentrated in Munster, Dublin and Belfast. These three locations saw over 75% of the conflicts fatalities, violence in Ulster, especially Belfast, was notable for its sectarian character and its high number of Catholic civilian victims. Both sides agreed to a truce on 11 July 1921, the post-ceasefire talks led to the signing of the Anglo-Irish Treaty on 6 December 1921. However, six counties remained within the United Kingdom. After the ceasefire, political and sectarian violence between republicans and loyalists continued in Northern Ireland for many months, in June 1922, disagreement among republicans over the Anglo-Irish Treaty led to an eleven-month civil war. The Irish Free State awarded 62,868 medals for service during the War of Independence, since the 1880s, Irish nationalists in the Irish Parliamentary Party had been demanding Home Rule, or self-government, from Britain. Fringe organisations, such as Arthur Griffiths Sinn Féin instead argued for some form of Irish independence, in turn, nationalists formed their own paramilitary organisation, the Irish Volunteers. But a significant minority of the Irish Volunteers opposed Irelands involvement in the war, the Volunteer movement split, a majority leaving to form the National Volunteers under Redmond

Irish Civil War
–
The civil war was waged between two opposing groups, Irish republicans and Irish nationalists, over the Anglo-Irish Treaty. The forces of the Provisional Government supported the Treaty, while the Republican opposition saw it as a betrayal of the Irish Republic, many of those who fought on both sides in the conflict had been members of the Irish Republican Army during the War of Independence. The Civil War was won by the Free State forces, which were armed with weapons provided by the British Government. The conflict may have claimed more lives than the War of Independence that preceded it, today, two of the main political parties in the Republic of Ireland, Fianna Fáil and Fine Gael, are direct descendants of the opposing sides of the war. The Anglo-Irish Treaty was agreed to end the 1919–1921 Irish War of Independence between the Irish Republic and the United Kingdom of Great Britain and Ireland, the treaty provided for a self-governing Irish state, having its own army and police. The Treaty also allowed Northern Ireland to opt out of the new state, the British suggested this dominion in secret correspondence even before treaty negotiations began, but Sinn Féin leader Éamon de Valera rejected the dominion. The treaty also stipulated that members of the new Irish Oireachtas would have to take the following Oath of Allegiance I and this oath was highly objectionable to many Irish Republicans. Furthermore, the partition of Ireland, which had already decided by the Westminster parliament in the Government of Ireland Act 1920, was effectively confirmed in the Anglo-Irish treaty. All these issues were the cause of a split in the IRA, however, anti-treaty militants in 1922 believed that the treaty would never deliver full Irish independence. The split over the treaty was deeply personal, many of the leaders on both sides had been close friends and comrades during the War of Independence. This made their disagreement over the treaty all the more bitter and he said that he felt deeply betrayed when de Valera refused to stand by the agreement that the plenipotentiaries had negotiated with David Lloyd George and Winston Churchill. De Valera, for his part, was furious that Collins, Dáil Éireann narrowly passed the Anglo-Irish Treaty by 64 votes to 57 on 7 January 1922. Following the Treatys ratification, in accordance with article 17 of the Treaty and its authority under the Treaty was to provide a provisional arrangement for the administration of Southern Ireland during the interval before the establishment of the Irish Free State. In accordance with the Treaty, the British Government transferred the powers, before the British Government transferred such powers, the members of the Provisional Government each signified in writing acceptance of. Upon the Treatys ratification, de Valera resigned as President of the Republic and he challenged the right of the Dáil to approve the treaty, saying that its members were breaking their oath to the Irish Republic. De Valera continued to promote a compromise whereby the new Irish Free State would be in association with the British Commonwealth rather than be a member of it. In early March, he formed the Cumann na Poblachta party while remaining a member of Sinn Féin and commenced a speaking tour of the more republican province of Munster on 17 March 1922. In a letter to the Irish Independent on 23 March, de Valera accepted the accuracy of their report of his comment about wading through blood, but deplored that the newspaper had published it

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

Indonesian National Revolution
–
It took place between Indonesias declaration of independence in 1945 and the Dutch recognition of Indonesias independence at the end of 1949. The Indonesian independence movement began in May 1908, which is commemorated as the Year of National Awakening, the struggle lasted for over four years and involved sporadic but bloody armed conflict, internal Indonesian political and communal upheavals, and two major international diplomatic interventions. Dutch military forces were able to control the towns, cities and industrial assets in Republican heartlands on Java and Sumatra. In 1949 international pressure on the Netherlands became such that, together with the existing partial military stalemate, the revolution marked the end of the colonial administration of the Dutch East Indies, except for Netherlands New Guinea. It also significantly changed ethnic castes, as well as reducing the power of many of the local rulers and it did not significantly improve the economic or political fortune of the majority of the population, although a few Indonesians were able to gain a larger role in commerce. Budi Utomo, Sarekat Islam and others pursued strategies of co-operation by joining the Dutch initiated Volksraad in the hope that Indonesia would be granted self-rule, others chose a non-cooperative strategy demanding the freedom of self-government from the Dutch East Indies colony. The most notable of these leaders were Sukarno and Mohammad Hatta, the occupation of Indonesia by Japan for three and a half years during World War II was a crucial factor in the subsequent revolution. The Netherlands had little ability to defend its colony against the Japanese army, in Java, and to a lesser extent in Sumatra, the Japanese spread and encouraged nationalist sentiment. Just as significantly for the subsequent revolution, the Japanese destroyed and replaced much of the Dutch-created economic, administrative, on 7 September 1944, with the war going badly for the Japanese, Prime Minister Koiso promised independence for Indonesia, but no date was set. For supporters of Sukarno, this announcement was seen as vindication for his collaboration with the Japanese, under pressure from radical and politicised pemuda groups, Sukarno and Hatta proclaimed Indonesian independence, on 17 August 1945, two days after the Japanese Emperor’s surrender in the Pacific. The following day, the Central Indonesian National Committee elected Sukarno as President, PROCLAMATION We, the people of Indonesia, hereby declare the independence of Indonesia. Matters which concern the transfer of power and other things will be executed by careful means, as the news spread, most Indonesians came to regard themselves as pro-Republican, and a mood of revolution swept across the country. External power had shifted, it would be weeks before Allied Forces entered Indonesia, the resulting power vacuums in the weeks following the Japanese surrender, created an atmosphere of uncertainty, but also one of opportunity for the Republicans. Many pemuda joined pro-Republic struggle groups, the most disciplined were soldiers from the Japanese-formed but disbanded Giyugun and Heiho groups. Many groups were undisciplined, due to both the circumstances of their formation and what they perceived as revolutionary spirit, in the first weeks, Japanese troops often withdrew from urban areas to avoid confrontations. To spread the message, pemuda set up their own radio stations and newspapers. On most islands, struggle committees and militia were set up, Republican leaders struggled to come to terms with popular sentiment, some wanted passionate armed struggle, others a more reasoned approach. Some leaders, such as the leftist Tan Malaka, spread the idea that this was a struggle to be led

Indo-Pakistani wars and conflicts
–
The Partition of British India came about in the aftermath of World War II, when both Great Britain and British India were dealing with the economic stresses caused by the war and its demobilisation. It was the intention of those who wished for a Muslim state to come from British India to have a partition between independent and equal Pakistan and Hindustan once independence came. As the Hindu and Muslim populations were scattered unevenly in the whole country, nearly one third of the Muslim population of British India remained in India. Inter-communal violence between Hindus, Sikhs and Muslims resulted in between 500,000 and 1 million casualties, princely-ruled territories, such as Kashmir and Hyderabad, were also involved in the Partition. Rulers of these territories had the choice of joining India or Pakistan, both India and Pakistan laid claim on Kashmir and thus it became the main point of conflict. The ruler of Kashmir, which had a Muslim majority population, the war, also called the First Kashmir War, started in October 1947 when Pakistan feared that the Maharajah of the princely state of Kashmir and Jammu would accede to India. Following partition, states were left to choose whether to join India or Pakistan or to remain independent, Jammu and Kashmir, the largest of the princely states, had a predominantly Muslim population ruled by the Hindu Maharaja Hari Singh. The UN Security Council passed the Resolution 47 on 22 April 1948, the fronts solidified gradually along what came to be known as the Line of Control. A formal cease-fire was declared at 23,59 on the night of 1 January 1949, India retaliated by launching a full-scale military attack on West Pakistan. The seventeen-day war caused thousands of casualties on both sides and witnessed the largest engagement of armored vehicles and the largest tank battle since World War II. The hostilities between the two ended after a ceasefire was declared following diplomatic intervention by the Soviet Union and USA. Both India and Pakistan claimed victory and this would culminate in the declaration of Independence of Bangladesh from the state system of Pakistan. Following Operation Searchlight and the 1971 Bangladesh atrocities, about 10 million Bengalis in East Pakistan took refuge in neighbouring India, India intervened in the ongoing Bangladesh liberation movement. After a large scale pre-emptive strike by Pakistan, full-scale hostilities between the two countries commenced, Pakistan attacked at several places along Indias western border with Pakistan, but the Indian Army successfully held their positions. The Indian Army quickly responded to the Pakistan Armys movements in the west and made initial gains. In the words of one Pakistani author, Pakistan lost half its navy, a quarter of its air force, commonly known as the Kargil War, this conflict between the two countries was mostly limited. During early 1999, Pakistani troops infiltrated across the Line of Control, India responded by launching a major military and diplomatic offensive to drive out the Pakistani infiltrators. Two months into the conflict, Indian troops had slowly retaken most of the ridges that were encroached by the infiltrators, according to official count, an estimated 75%–80% of the intruded area and nearly all high ground was back under Indian control

Greek Civil War
–
The Greek Civil War was fought in Greece from 1946 to 1949 between the Greek government army, and the Democratic Army of Greece. The fighting resulted in the defeat of the Communist insurgents by the government forces, the civil war resulted from a highly polarized struggle between left and right ideologies that started in 1943. From 1944 each side targeted the power vacuum that the end of German-Italian occupation during World War II left, the struggle became one of the first conflicts of the Cold War and represents the first example of Cold War power postwar involvement in the internal politics of a foreign country. The first signs of the war occurred in 1942 to 1944. The immediate prelude of the war took place in Athens, on December 3,1944. A bloody battle erupted after Greek government gendarmes, with British forces standing in the background, opened fire on a massive unarmed pro-EAM rally, killing 28 demonstrators and injuring dozens. The rally had been organised against the impunity of the collaborators and the general disarmament ultimatum, signed by Ronald Scobie, the battle lasted 33 days and resulted in the defeat of the EAM after the heavily reinforced British forces sided with the Greek government. All the while, White Terror was unleashed against the supporters of the left, the war erupted in 1946, when forces of former ELAS partisans who found shelter in their hideouts and were controlled by the KKE organized the DSE and its High Command headquarters. The Communists formed a government in December 1947 and used the DSE as the military branch of this government. The neighboring communist states of Albania, Yugoslavia and Bulgaria offered logistical support to this provisional government, the final victory of the western-allied government forces led to Greeces membership in NATO and helped to define the ideological balance of power in the Aegean Sea for the entire Cold War. Western leaders encouraged and even coerced King George II of Greece to appoint a moderate cabinet, nevertheless, the exiled governments inability to influence affairs inside Greece rendered it irrelevant in the minds of most Greek people. At the same time, the Germans set up a collaborationist government in Athens, the puppet regime was further undermined when economic mismanagement in wartime conditions created runaway inflation, acute food shortages and famine among the civilian population. The power vacuum that the occupation created was filled by several resistance movements that ranged from royalist to communist ideologies, resistance was born first in eastern Macedonia and Thrace, where Bulgarian troops occupied Greek territory. Soon large demonstrations were organized in cities by the Defenders of Northern Greece. However, the largest group to emerge was the National Liberation Front, proclaiming that it followed the Soviet policy of creating a broad united front against fascism, EAM won the support of many noncommunist patriots. These resistance groups launched attacks against the powers and set up large espionage networks. When liberation came in October 1944, Greece was in a state of crisis, although controlled by the KKE, the organization had democratic republican rhetoric. Its military wing, the Greek Peoples Liberation Army was founded in February 1942, Aris Velouchiotis, a member of KKEs Central Committee, was nominated Chief of the ELAS High Command

Malayan Emergency
–
Malayan Emergency was the colonial governments term for the conflict. The MNLA termed it the Anti-British National Liberation War, the rubber plantations and tin-mining industries had pushed for the use of the term emergency since their losses would not have been covered by Lloyds insurers if it had been termed a war. Despite the communists defeat in 1960, communist leader Chin Peng renewed the insurgency against the Malaysian government in 1967 and he fled to exile in Thailand, where he lived until his death on 16 September 2013. The Malayan economy relied on the export of tin and rubber, when the British took control of the Malayan economy, they imposed taxes on some Malayan goods, affecting their traditional industries. This led to an increase in poverty for the Malayan people, many Chinese people found employment in tin mines or fields responsible for the trade of materials. This heightened inter-ethnic tensions as the Malay people found that ethnic Chinese had replaced them in certain jobs and this forced many Malays into the rubber industry, which in turn was heavily dependent upon volatile world prices. Economic tension intensified during the Second World War. The Japanese occupation of Malaya began in 1941 and from that point onwards the “export of primary products was limited to the small amounts required for the Japanese economy. ”This led to large areas of rubber plantations being abandoned. The latter was progressively affected by a shortage of parts for machines. Rice imports, which made up a portion of the Malayan diet, fell rapidly due to limited trade. Many people believed that the British would soon return and ‘save’ them so they did not attempt to learn the skills that would be essential for survival. This then led to famine in Malaya from 1942. The withdrawal of Japan at the end of World War II left the British Malayan economy disrupted, problems included unemployment, low wages, and high levels of food inflation, well above the healthy rate of 2–3%. The Malayan Communist Party began to use the failing economy as a tool of propaganda against the British, the British had not addressed the underlying economic problems that were now worse within Malaya than they had ever been. There was considerable labour unrest and a number of strikes occurred between 1946 and 1948. One example of this was a 24-hour general strike organised by the MCP on 29 January 1946, during this time, the British administration was attempting to organise Malayas economy, as revenue from Malayas tin and rubber industries was important to Britains own post-war recovery. Protesters were dealt with harshly, by measures including arrests and deportations, in turn, protesters became increasingly militant. In 1947, alone, the communists in Malaya organised a further 300 strikes, on 16 June 1948, the first overt act of the war took place when three European plantation managers were killed at Sungai Siput, Perak

First Indochina War
–
The First Indochina War began in French Indochina on 19 December 1946 and lasted until 1 August 1954. Fighting between French forces and their Viet Minh opponents in the South dated from September 1945, Japanese forces located south of that line surrendered to him and those to the north surrendered to Generalissimo Chiang Kai-shek. In September 1945, Chinese forces entered Tonkin and a small British task force landed at Saigon, the Chinese accepted the Vietnamese government under Ho Chi Minh, then in power in Hanoi. The British refused to do likewise in Saigon, and deferred to the French there from the outset, on V-J Day, September 2, Ho Chi Minh had proclaimed in Hanoi the establishment of the Democratic Republic of Vietnam. On 23 September 1945, with the knowledge of the British Commander in Saigon, French forces overthrew the local DRV government, guerrilla warfare began around Saigon immediately. The first few years of the war involved a low-level rural insurgency against the French, French Union forces included colonial troops from the whole former empire, French professional troops and units of the French Foreign Legion. The use of metropolitan recruits was forbidden by the government to prevent the war from becoming more unpopular at home. It was called the dirty war by leftists in France, the strategy of pushing the Viet Minh into attacking well-defended bases in remote parts of the country at the end of their logistical trails was validated at the Battle of Nà Sản. However, this base was relatively weak because of a lack of concrete and this combination proved fatal for this base defenses, culminating in a decisive French defeat at the Battle of Dien Bien Phu. The south continued under Emperor Bảo Đại, a year later, Bảo Đại would be deposed by his prime minister, Ngô Đình Diệm, creating the Republic of Vietnam. Soon an insurgency, backed by the North, developed against Diệms government, the conflict gradually escalated into the Vietnam War. Vietnam was absorbed into French Indochina in stages between 1858 and 1887, nationalism grew until World War II provided a break in French control. Early Vietnamese resistance centered on the intellectual Phan Bội Châu, Châu looked to Japan, which had modernized and was one of the few Asian nations to successfully resist European colonization. With Prince Cường Để, Châu started two organizations in Japan, the Duy Tân hội and Vietnam Cong Hien Hoi, due to French pressure, Japan deported Phan Bội Châu to China. Witnessing Sun Yat-sens 1911 nationalist revolution, Châu was inspired to commence the Viet Nam Quang Phục Hội movement in Guangzhou, from 1914 to 1917, he was imprisoned by Yuan Shikais counterrevolutionary government. In 1925, he was captured by French agents in Shanghai, due to his popularity, Châu was spared from execution and placed under house arrest until his death in 1940. In September 1940, shortly after Phan Bội Châus death, Japan launched its invasion of French Indochina, keeping the French colonial administration, the Japanese ruled from behind the scenes in a parallel of Vichy France. As far as Vietnamese nationalists were concerned, this was a double-puppet government, Emperor Bảo Đại collaborated with the Japanese, just as he had with the French, ensuring his lifestyle could continue

Korean War
–
The Korean War began when North Korea invaded South Korea. The United Nations, with the United States as the principal force, China came to the aid of North Korea, and the Soviet Union gave some assistance. Korea was ruled by Japan from 1910 until the days of World War II. In August 1945, the Soviet Union declared war on Japan, as a result of an agreement with the United States, U. S. forces subsequently moved into the south. By 1948, as a product of the Cold War between the Soviet Union and the United States, Korea was split into two regions, with separate governments, both governments claimed to be the legitimate government of all of Korea, and neither side accepted the border as permanent. The conflict escalated into open warfare when North Korean forces—supported by the Soviet Union, on that day, the United Nations Security Council recognized this North Korean act as invasion and called for an immediate ceasefire. On 27 June, the Security Council adopted S/RES/83, Complaint of aggression upon the Republic of Korea and decided the formation, twenty-one countries of the United Nations eventually contributed to the UN force, with the United States providing 88% of the UNs military personnel. After the first two months of war, South Korean forces were on the point of defeat, forced back to the Pusan Perimeter, in September 1950, an amphibious UN counter-offensive was launched at Inchon, and cut off many North Korean troops. Those who escaped envelopment and capture were rapidly forced back north all the way to the border with China at the Yalu River, at this point, in October 1950, Chinese forces crossed the Yalu and entered the war. Chinese intervention triggered a retreat of UN forces which continued until mid-1951, after these reversals of fortune, which saw Seoul change hands four times, the last two years of fighting became a war of attrition, with the front line close to the 38th parallel. The war in the air, however, was never a stalemate, North Korea was subject to a massive bombing campaign. Jet fighters confronted each other in combat for the first time in history. The fighting ended on 27 July 1953, when an armistice was signed, the agreement created the Korean Demilitarized Zone to separate North and South Korea, and allowed the return of prisoners. However, no treaty has been signed, and the two Koreas are technically still at war. Periodic clashes, many of which are deadly, continue to the present, in the U. S. the war was initially described by President Harry S. Truman as a police action as it was an undeclared military action, conducted under the auspices of the United Nations. In South Korea, the war is referred to as 625 or the 6–2–5 Upheaval. In North Korea, the war is referred to as the Fatherland Liberation War or alternatively the Chosǒn War. In China, the war is called the War to Resist U. S

Suez Crisis
–
The Suez Crisis, also named the Tripartite Aggression and the Kadesh Operation or Sinai War, was an invasion of Egypt in late 1956 by Israel, followed by the United Kingdom and France. The aims were to regain Western control of the Suez Canal, after the fighting had started, political pressure from the United States, the Soviet Union, and the United Nations led to a withdrawal by the three invaders. The episode humiliated Great Britain and France and strengthened Nasser, on October 29, Israel invaded the Egyptian Sinai. Britain and France issued a joint ultimatum to cease fire, which was ignored, on November 5, Britain and France landed paratroopers along the Suez Canal. The Egyptian forces were defeated, but they did block the canal to all shipping and it later became clear that the Israeli invasion and the subsequent Anglo-French attack had been planned beforehand by the three countries. The three allies had attained a number of their objectives, but the Canal was now useless and heavy political pressure from the United States. U. S. President Dwight D. Eisenhower had strongly warned Britain not to invade, historians conclude the crisis signified the end of Great Britains role as one of the worlds major powers. The Suez Canal was closed from October 1956 until March 1957, Israel fulfilled some of its objectives, such as attaining freedom of navigation through the Straits of Tiran. The Suez Canal was opened in 1869, after ten years of work financed by the French, the canal instantly became strategically important, as it provided the shortest ocean link between the Mediterranean and the Indian Ocean. The canal eased commerce for trading nations and particularly helped European colonial powers to gain, in 1875, as a result of debt and financial crisis, the Egyptian ruler was forced to sell his shares in the canal operating company to the British government of Benjamin Disraeli. They were willing buyers and obtained a 44 percent share in the operations for less than £4 million. With the 1882 invasion and occupation of Egypt, the United Kingdom took de facto control of the country as well as the canal proper, the 1888 Convention of Constantinople declared the canal a neutral zone under British protection. In ratifying it, the Ottoman Empire agreed to international shipping to pass freely through the canal, in time of war. The Convention came into force in 1904, the year as the Entente cordiale between Britain and France. Following the Japanese surprise attack on the Russian Pacific Fleet based at Port Arthur, the British denied the Russian fleet use of the canal and forced it to steam around Africa, giving the Japanese forces time to consolidate their position in East Asia. The importance of the canal as an intersection was again apparent during the First World War. The attempt by German and Ottoman forces to storm the canal in February 1915 led the British to commit 100,000 troops to the defense of Egypt for the rest of the war. The canal continued to be strategically important after the Second World War as a conduit for the shipment of oil, petroleum business historian Daniel Yergin wrote of the period, In 1948, the canal abruptly lost its traditional rationale

Mau Mau Uprising
–
The Mau Mau Uprising, also known as the Mau Mau Rebellion, Mau Mau Revolt, or Kenya Emergency, was a military conflict that took place in British Kenya between 1952 and 1960. The capture of rebel leader Dedan Kimathi on 21 October 1956 signalled the defeat of the Mau Mau, the British, meanwhile, could draw upon their ongoing efforts to put down another rebellion in Malaya. The uprising created a rift between the European colonial community in Kenya and the metropole, but also resulted in violent divisions within the Kikuyu community, the financial cost of the uprising to the former colony amounted to £55 million. This followed a June 2013 decision by Britain to compensate more than 5,000 Kenyans it tortured and abused during the Mau Mau insurgency, the origin of the term Mau Mau is uncertain. According to some members of Mau Mau, they never referred to themselves as such, instead preferring the military title Kenya Land, majdalany goes on to state that the British simply used the name as a label for the Kikuyu ethnic community without assigning any specific definition. As the movement progressed, a Swahili backronym was adopted, Mzungu Aende Ulaya, Mwafrika Apate Uhuru meaning Let the foreigner go back abroad, let the African regain independence. J. M. Kariuki also wrote that the term Mau Mau was adopted by the rebellion in order to counter what they regarded as colonial propaganda. Though declared a colony in 1920, the formal British colonial presence in Kenya began with a proclamation on 1 July 1895, even before 1895, however, Britains presence in Kenya was marked by dispossession and violence. During the period in which Kenyas interior was being opened up for British settlement, there was plenty of conflict. If the H. of C. gets hold of it, surely it cannot be necessary to go on killing these defenceless people on such an enormous scale. Kenyan opposition to British imperialism existed from the start of the British occupation, in military terms, none of the armed uprisings during the beginning of British colonialism in Kenya were successful. Nor did Kenyan protest end with the Mau Mau uprising, in the years that followed, the British presence exacerbated existing disharmony and instability in Kikuyu society. A feature of all settler societies during the period was the ability of European settlers to obtain for themselves a disproportionate share in land ownership. Kenya was no exception, with the first settlers arriving in 1902 as part of Governor Charles Eliots plan to have a settler economy pay for the recently completed Uganda Railway. In particular, the British governments 1925 East Africa Commission noted and this tribe was moved backwards and forwards so as to secure for the Crown areas which could be granted to Europeans. Coupled with an increasing native Kenyan population, the land became an increasingly bitter point of contention.5 square miles of their potentially highly valuable land alienated. In terms of lost acreage, the Masai and Nandi were the biggest losers of land, the Kikuyu did mount a legal challenge to the expropriation of their land, but a Kenya High Court decision of 1921 reaffirmed its legality. The colonial government and White farmers also wanted cheap labour which, for a period, native Kenyan labourers were in one of three categories, squatter, contract, or casual

Sino-Indian War
–
The Sino-Indian War, also known as the Sino-Indian Border Conflict, was a war between China and India that occurred in 1962. A disputed Himalayan border was the pretext for war. There had been a series of violent border incidents after the 1959 Tibetan uprising, Chinese troops advanced over Indian forces in both theatres, capturing Rezang la in Chushul in the western theatre, as well as Tawang in the eastern theatre. The war ended when China declared a ceasefire on 20 November 1962, Indian posts and patrols were removed from Aksai Chin, which came under direct Chinese control after the end of the conflict. It was the 3rd major loss of land for India after losing Gilgit-Baltistan, the Sino-Indian War is notable for the harsh mountain conditions under which much of the fighting took place, entailing large-scale combat at altitudes of over 4,000 metres. The Sino-Indian War was also noted for the non-deployment of the navy or air force by either the Chinese or Indian side. China and India shared a border, sectioned into three stretches by Nepal, Sikkim, and Bhutan, which follows the Himalayas between Burma and what was then West Pakistan. A number of disputed regions lie along this border, at its western end is the Aksai Chin region, an area the size of Switzerland, that sits between the Chinese autonomous region of Xinjiang and Tibet. The eastern border, between Burma and Bhutan, comprises the present Indian state of Arunachal Pradesh, both of these regions were overrun by China in the 1962 conflict. Most combat took place at high altitudes, the Aksai Chin region is a desert of salt flats around 5,000 metres above sea level, and Arunachal Pradesh is mountainous with a number of peaks exceeding 7,000 metres. The Chinese Army had possession of one of the highest ridges in the regions, the high altitude and freezing conditions also cause logistical and welfare difficulties, in past similar conflicts harsh conditions have caused more casualties than have enemy action. The Sino-Indian War was no different, with troops on both sides dying in the freezing cold. The cause of the war was a dispute over the sovereignty of the widely separated Aksai Chin, Aksai Chin, claimed by India to belong to Kashmir and by China to be part of Xinjiang, contains an important road link that connects the Chinese regions of Tibet and Xinjiang. Chinas construction of road was one of the triggers of the conflict. The western portion of the Sino-Indian boundary originated in 1834, with the Sikh Confederacys conquest of Ladakh, in 1842, the Sikh Confederacy, which at the time ruled over much of Northern India, signed a treaty which guaranteed the integrity of its existing borders with its neighbours. The boundaries at its two extremities, Pangong Lake and Karakoram Pass, were defined, but the Aksai Chin area in between lay undefined. W. H. Johnson, a servant with the Survey of India, proposed the Johnson Line in 1865. Johnson presented this line to the Maharaja of Kashmir, who claimed the 18,000 square kilometres contained within

Bangladesh Liberation War
–
It resulted in the independence of the Peoples Republic of Bangladesh. The war began after the Pakistani military junta based in West Pakistan launched Operation Searchlight against the people of East Pakistan on the night of 25 March 1971 and it pursued the systematic elimination of nationalist Bengali civilians, students, intelligentsia, religious minorities and armed personnel. The junta annulled the results of the 1970 elections and arrested Prime Minister-elect Sheikh Mujibur Rahman, rural and urban areas across East Pakistan saw extensive military operations and air strikes to suppress the tide of civil disobedience that formed following the 1970 election stalemate. The Pakistan Army, which had the backing of Islamists, created radical religious militias – the Razakars, Al-Badr, members of the Pakistani military and supporting militias engaged in mass murder, deportation and genocidal rape. The capital Dhaka was the scene of massacres, including the Dhaka University killings. An estimated 10 million Bengali refugees fled to neighbouring India, while 30 million were internally displaced, sectarian violence broke out between Bengalis and Urdu-speaking immigrants. An academic consensus prevails that the committed by the Pakistani military were a genocide. The Bangladeshi Declaration of Independence was proclaimed from Chittagong by members of the Mukti Bahini – the national liberation army formed by Bengali military, paramilitary, the East Bengal Regiment and the East Pakistan Rifles played a crucial role in the resistance. Led by General M. A. G. Osmani and eleven sector commanders and they liberated numerous towns and cities in the initial months of the conflict. The Pakistan Army regained momentum in the monsoon, Bengali guerrillas carried out widespread sabotage, including Operation Jackpot against the Pakistan Navy. The nascent Bangladesh Air Force flew sorties against Pakistani military bases, by November, the Bangladesh forces restricted the Pakistani military to its barracks during the night. They secured control of most parts of the countryside, the Provisional Government of Bangladesh was formed on 17 April 1971 in Mujibnagar and moved to Calcutta as a government in exile. Bengali members of the Pakistani civil, military and diplomatic corps defected to the Bangladeshi provisional government, thousands of Bengali families were interned in West Pakistan, from where many escaped to Afghanistan. Bengali cultural activists operated the clandestine Free Bengal Radio Station, the plight of millions of war-ravaged Bengali civilians caused worldwide outrage and alarm. The Indian state led by Indira Gandhi provided substantial diplomatic, economic, British, Indian and American musicians organised the worlds first benefit concert in New York City to support the Bangladeshi people. India joined the war on 3 December 1971, after Pakistan launched preemptive air strikes on North India, the subsequent Indo-Pakistani War witnessed engagements on two war fronts. With air supremacy achieved in the theatre and the rapid advance of the Allied Forces of Bangladesh and India. The war changed the landscape of South Asia, with the emergence of Bangladesh as the seventh-most populous country in the world

Nepalese Civil War

The Maoist was an armed conflict against The Government of Nepal fought from 1996 to 2006. The rebellion was launched by the Communist Party of Nepal on 13 February 1996 with the aim of overthrowing the Nepalese monarchy. It ended with the Comprehensive Peace Accord signed on 21 November 2006, More than 19,000 people were killed during the conflict. National Geographic Magazine, p.54, November 2005, douglas lists the following figures, Nepalis killed by Maoists from 1996 to 2005,4,500. Nepalis killed by government in same period,8,200. however, communist groups uncomfortable with the alliance between ULF and Congress formed a parallel front, the United National Peoples Movement. The UNPM called for elections to a Constituent Assembly, and rejected compromises made by ULF, in November 1990 the Communist Party of Nepal was formed, including key elements of constituents of UNPM. The new party held its first convention in 1991, the adopted a line of protracted armed struggle on the route to a new democratic revolution, the CPN set up Samyukta Jana Morcha, with Baburam Bhattarai as its head, as an open front ten contest elections. In the 1991 elections, SJM became the force in the Nepali parliament. However, disagreements surged regarding which tactics were to be used by the party, One sector argued for immediate armed revolution whereas others claimed that Nepal was not yet ripe for armed struggle. In 1994 CPN/SJM was split in two, the militant faction later renamed itself the Communist Party of Nepal. The Maoists labeled the government forces feudal forces, and included in this accusation was the monarchy, the armed struggle began soon afterward with simultaneous attacks on remote police stations and district headquarters. Initially, the Nepali government mobilized the Nepal Police to contain the insurgency, the Royal Nepal Army was not involved in direct fighting because the conflict was regarded as a matter for the police to sustain control. Furthermore, controversy regarding the army not assisting the police during insurgent attacks in remote areas. The popularly elected prime minister resigned his post, due to the refusal of the Royal Army to take part in the conflict and this situation changed dramatically in 2002 when the first session of peace talks failed and the Maoists attacked an army barracks in Dang District in western Nepal. Overnight, the army was unleashed against the insurgents, mobilizing both tanks and artillery and this material support to the Nepali government dried up after King Gyanendra seized full control in February 2005 to get rid of civil war for once and all. The government responded to the rebellion by banning provocative statements about the monarchy, imprisoning journalists, several rounds of negotiations, accompanied by temporary cease-fires, were held between the insurgents and the government. The government categorically rejected the demand for an election to the constituent assembly. At the same time, the Maoists refused to recognize the installation of a constitutional monarchy, throughout war, the government controlled the main cities and towns, whilst the Maoist dominated the rural areas

The word bullet is a firearm term. A bullet is a projectile expelled from the barrel of a firearm, the term is from Middle French and originated as the diminutive of the word boulle which means small ball. Bullets are made of a variety of materials and they are available singly as they would be used in muzzle loading and cap and ball firearms, as part of a paper cartridge, and much more commonly as a component of metallic cartridges. Bullets are made in a numbers of styles and constructions depending on how they will be used. Many bullets have specialized functions, such as hunting, target shooting, training, defense, a bullet is not a cartridge. In paper and metallic cartridges a bullet is one component of the cartridge, bullet sizes are expressed by their weight and diameter in both English and Metric measurement systems. For example.22 caliber 55 grain bullets or 5. 56mm 55 grain bullets are the same caliber, the word bullet is often used colloquially to refer to a cartridge, which is a combination of the bullet, paper or metallic case/shell, powder, and primer. This use of bullet, when cartridge is intended, leads to confusion when the components of a cartridge are discussed or intended, the bullets used in many cartridges are fired at a muzzle velocity faster than the speed of sound. Meaning they are supersonic and thus can travel a substantial distance, bullet speed through air depends on a number of factors such as barometric pressure, humidity, air temperature, and wind speed. Subsonic cartridges fire bullets slower than the speed of sound and so there is no sonic crack and this means that a subsonic cartridge such as.45 ACP can be effectively suppressed to be substantially quieter than a supersonic cartridge such as the.223 Remington. Bullets do not normally contain explosives, but damage the target by impact. The first use of gunpowder in Europe was recorded in 1247 and it had been used in China for hundreds of years. Later in 1364 hand cannon appeared, early projectiles were made of stone. Stone was used in cannon and hand cannon, in cannon it was eventually found that stone would not penetrate stone fortifications which gave rise to the use of heavier metals for the round projectiles. Hand cannon projectiles developed in a similar following the failure of stone from siege cannon. The first recorded instance of a ball from a hand cannon penetrating armor occurred in 1425. In this photograph of shot retrieved from the wreck of the Mary Rose which was sunk in 1545, the round shot are clearly of different sizes and some are stone while others are cast iron. The development of the hand culverin and matchlock arquebus brought about the use of cast lead balls as projectiles, bullet is derived from the French word boulette, which roughly means little ball

Grain (unit)
–
A grain is a unit of measurement of mass, and, for the troy grain, equal to exactly 7001647989100000000♠64.79891 milligrams. It is nominally based upon the mass of a seed of a cereal. From the Bronze Age into the Renaissance the average masses of wheat, rather, expressions such as thirty-two grains of wheat, taken from the middle of the ear appear to have been ritualistic formulas, essentially the premodern equivalent of legal boilerplate. Another book states that Captain Henry Kater, of the British Standards Commission, the grain was the legal foundation of traditional English weight systems, and is the only unit that is equal throughout the troy, avoirdupois, and apothecaries systems of mass. The unit was based on the weight of a grain of barley. The fundamental unit of the pre-1527 English weight system known as Tower weights, was a different sort of known as the wheat grain. The Tower wheat grain was defined as exactly 45⁄64 of a troy grain.79891 milligrams, 7000100000000000000♠1 gram is approximately 7001154323600000000♠15.43236 grains. The unit formerly used by jewellers to measure pearls, diamonds, or other stones, called the jewellers grain or pearl grain, is equal to 1⁄4 of a carat. The grain was also the name of a traditional French unit equal to 6995531150000000000♠53.115 mg. In both British Imperial and U. S. customary units, there are precisely 7,000 grains per avoirdupois pound, the grain is commonly used to measure the mass of bullets and propellants. The term also refers to a particle of gunpowder, the size of which varies according to requirements. In archery, the grain is the unit used to weigh arrows. In dentistry, gold foil, used as a material to restore teeth, is measured in grains, in North America, the hardness of water is often measured in grains per US gallon of calcium carbonate equivalents. Otherwise, water hardness is measured in the metric unit parts per million, one grain per US gallon is approximately 6995171000000000000♠17.1 ppm. Soft water contains 1–4 gpg of calcium carbonate equivalents, while hard water contains 11–20 gpg, though no longer recommended, grains are still used occasionally in medicine as part of the apothecaries system, especially in prescriptions for older medicines such as aspirin or phenobarbital. For example, the dosage of a standard 6996325000000000000♠325 mg tablet of aspirin is sometimes given as 7000500000000000000♠5 grains, in that example the grain is approximated to 6995650000000000000♠65 mg, though the grain can also be approximated to 6995600000000000000♠60 mg, depending on the medication and manufacturer. The apothecaries system has its own system of notation, in which the symbol or abbreviation is followed by the quantity in lower case Roman numerals. For amounts less than one, the quantity is written as a fraction, or for one half, therefore, a prescription for tablets containing 325 mg of aspirin and 30 mg of codeine can be written ASA gr

Rifling
–
In firearms, rifling consists of helical grooves in the internal surface of a guns barrel, which impart a spin to a projectile around its long axis. This spin serves to stabilize the projectile, improving its aerodynamic stability. Rifling is often described by its twist rate, which indicates the distance the rifling takes to complete one revolution, such as 1 turn in 10 inches. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will be rotating at a spin rate. Barrels intended for long, small-diameter bullets, such as the ultra-low-drag, 80-grain 0.223 inch bullets, extremely long projectiles such as flechettes may require high twist rates, these projectiles must be inherently stable, and are often fired from a smoothbore barrel. Muskets were smoothbore, large caliber weapons using ball-shaped ammunition fired at low velocity. Due to the high cost and great difficulty of manufacturing, and the need to load readily from the muzzle. Consequently, on firing the ball bounced off the sides of the barrel when fired, barrel rifling was invented in Augsburg, Germany in 1498. In 1520 August Kotter, an armourer of Nuremberg, Germany improved upon this work, though true rifling dates from the mid-16th century, it did not become commonplace until the nineteenth century. The most successful weapons using rifling with black powder were breech loaders such as the Queen Anne pistol, the grooves most commonly used in modern rifling have fairly sharp edges. More recently, polygonal rifling, a throwback to the earliest types of rifling, has become popular, polygonal barrels tend to have longer service lives because the reduction of the sharp edges of the land reduces erosion of the barrel. Supporters of polygonal rifling also claim higher velocities and greater accuracy, polygonal rifling is currently seen on pistols from CZ, Heckler & Koch, Glock, Tanfoglio, and Kahr Arms, as well as the Desert Eagle. Such guns have achieved significant increases in velocity and range. Examples include the South African G5 and the German PzH2000, gain-twist rifling begins with very little change in the projectiles angular momentum during the first few inches of bullet travel after ignition during the transition from chamber to throat. This enables the bullet to remain undisturbed and trued to the case mouth. After engaging the rifling the bullet is progressively subjected to accelerated angular momentum as burning powder propels it down the barrel. By only gradually increasing the rate, torque is spread along a much longer section of barrel. Gain-twist rifling was used as early as the American Civil War, colt Army and Navy revolvers both employed gain-twist rifling

Primer (firearms)
–
In firearm ballistics, the primer is a component of pistol, rifle, and shotgun rounds. Early primers were simply the same black powder used to fire the weapon and this external powder was connected though a tube in the barrel that led to the main charge. As powder wont burn when wet, this led to difficulty, or even the inability, modern primers are shock sensitive chemicals. In smaller weapons the primer is usually integrated into the rear of a cartridge, in larger weapons like cannon the primer is a separate component placed inside the barrel to the rear of the main propellant charge. The first step to firing a firearm of any sort is igniting the propellant, the earliest firearms were cannons, which were simple closed tubes. There was an aperture, the touchhole, drilled in the closed end of the tube. This hole was filled with finely ground powder, which was ignited with a hot ember or torch. With the advent of firearms, this became an undesirable way of firing a gun. The first attempt to make the process of firing a small arm easier was the matchlock, the matchlock incorporated a lock that was actuated by a trigger, originally called a tricker. The lock was a lever which pivoted when pulled. The match was a burning fuse made of plant fibers that were soaked in a solution of nitrates, charcoal, and sulfur. This slow-match was ignited before the gun was needed, and it would slowly burn, after the gun was loaded and the touchhole primed with powder, the burning tip of the match was positioned so that the lock would bring it into contact with the touchhole. To fire the gun, it was aimed and the trigger pulled and this brought the match down to the touchhole, igniting the powder. With careful attention the slow-burning match could be burning for long periods of time. The next revolution in technology was the wheel-lock. It used a spring-loaded, serrated steel wheel which rubbed against a piece of iron pyrite, a key was used to wind the wheel and put the spring under tension. Once tensioned, the wheel was held in place by a trigger, when the trigger was pulled, the serrated edge of the steel rubbed against the pyrite, generating sparks. These sparks were directed into a pan, called the flash pan, the flashpan usually was protected by a spring-loaded cover that would slide out of the way when the trigger was pulled, exposing the powder to the sparks

Rim (firearms)
–
A rim is an external flange that is machined, cast, molded, stamped or pressed around the bottom of a firearms cartridge. Thus, rimmed cartridges are sometimes called flanged cartridges, almost all cartridges feature an extractor or headspacing rim, in spite of the fact that some cartridges are known as rimless cartridges. These types are rimmed, rimless, semi-rimmed, rebated rim and these categories describe the size of the rim in relation to the base of the case. The rimmed cartridge, sometimes called flanged cartridge, is the oldest of the types and has a rim that is larger in diameter than the base of the cartridge. Rimmed cartridges use the rim to hold the cartridge in the chamber of the firearm, because the rimmed cartridge headspaces on the rim, the case length is of less importance than rimless cartridges. This allows some firearms chambered for similar rimmed cartridges to safely chamber and fire shorter cartridges, rimmed cartridges are well suited to certain types of actions, such as revolvers, where the rim helps hold the cartridge in position, and break-action firearms. Semi-automatic handguns have been chambered in rimmed cartridges as well, for example a LAR Grizzly or Desert Eagle in.357 or.44 Magnum, under the metric cartridge designation system, a capitalized R added at the end of the designation denotes a rimmed cartridge. For example,7. 62×54mmR is a cartridge, while 7. 62×51mm is a rimless cartridge.45 Auto Rim. Examples of rimmed handgun cartridges include the.38 Special.357 Magnum, rimmed rifle cartridge examples include the.22 Hornet.303 British and 7. 62×54mmR. Rimless cases are not well suited to break-open and revolver actions, though they can be used with modifications, such as a spring-loaded extractor or, in a revolver. Crimping affects the length of the cartridge, and thus cannot be used on cartridges which headspace on the case mouth. Examples of rimless handgun cartridges include the 9mm Parabellum.40 S&W, rimless rifle examples include the.223 Remington.308 Winchester. 30-06 Springfield and 7. 92×57mm Mauser. On a semi-rimmed case the rim projects slightly beyond the base of the case, the tiny rim provides minimal interference feeding from a box magazine, while still providing enough surface to headspace on. Semi-rimmed cases are less common than the other types, if the chamber is cut shallow, so the case headspaces off the mouth, the rim is used for extraction only, a standard chamber will use the rim for both headspacing and extraction. Examples of more commonly encountered rimless handgun cartridges are.25 ACP.32 ACP and.38 ACP, while the.308 Marlin Express.338 Marlin Express and.444 Marlin are rifle cartridges that are semi-rimmed. Rebated rim cartridges have a rim that is smaller in diameter than the base of the case. Functionally the same as a case, the rebated rim provides some additional benefits when considered in conjunction with other cartridges. One example of a rebated rim cartridge is the.50 Action Express, by using the same rim dimensions as the.44 Magnum, a Desert Eagle could be converted from.44 Magnum to.50 AE by merely changing the barrel and magazine

Cartridge (firearms)
–
Military and commercial producers continue to pursue the goal of caseless ammunition. A cartridge without a bullet is called a blank, One that is completely inert is called a dummy. Some artillery ammunition uses the same concept as found in small arms. In other cases, the shell is separate from the propellant charge. In popular use, the bullet is often misused to refer to a complete cartridge. The cartridge case seals a firing chamber in all directions excepting the bore, a firing pin strikes the primer and ignites it. The primer compound deflagrates, it does not detonate, a jet of burning gas from the primer ignites the propellant. Gases from the burning powder pressurize and expand the case to seal it against the chamber wall and these propellant gases push on the bullet base. In response to pressure, the bullet will move in the path of least resistance which is down the bore of the barrel. After the bullet leaves the barrel, the pressure drops to atmospheric pressure. The case, which had been expanded by chamber pressure. This eases removal of the case from the chamber, brass is a commonly used case material because it is resistant to corrosion. A brass case head can be work-hardened to withstand the pressures of cartridges. The neck and body portion of a case is easily annealed to make the case ductile enough to allow reforming so that it can be reloaded many times. Steel is used in some plinking ammunition, as well as in military ammunition. Steel is less expensive than brass, but it is not feasible to reload, Military forces typically consider small arms cartridge cases to be disposable, one-time-use devices. However, case weight affects how much ammunition a soldier can carry, conversely, steel is more susceptible to contamination and damage so all such cases are varnished or otherwise sealed against the elements. One downside caused by the strength of steel in the neck of these cases is that propellant gas can blow back past the neck

Gunpowder
–
Gunpowder, also known as black powder, is the earliest known chemical explosive. It is a mixture of sulfur, charcoal, and potassium nitrate, the sulfur and charcoal act as fuels, and the saltpeter is an oxidizer. Black powder firearms are in limited use today in hunting, shooting, Black powder has been replaced for most industrial uses by high explosives such as dynamite. Black powder is assigned the UN number UN0027 and has a class of 1. 1D. It has a point of approximately 427–464 °C. The specific flash point may vary based on the composition of the gunpowder. Gunpowders specific gravity is 1. 70–1.82 or 1. 92–2.08, Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate at subsonic speeds, whereas high explosives detonate, ignition of the powder packed behind a bullet must generate enough pressure to force it from the muzzle at high speed, but not enough to rupture the gun barrel. Gunpowder thus makes a good propellant, but is suitable for shattering rock or fortifications. Gunpowder was widely used to fill artillery shells and in mining and civil engineering to blast rock until the half of the 19th century. Black powder is used as a delay element in various munitions where its slow-burning properties are valuable. The spread of gunpowder across Asia from China is widely attributed to the Mongols, the earliest record of a written formula for gunpowder appears in the 11th century Song dynasty text, Wujing Zongyao. This discovery led to the invention of fireworks and the earliest gunpowder weapons in China, in the centuries following the Chinese discovery, gunpowder weapons began appearing in the Muslim world and Europe. The technology spread from China through the Middle East or Central Asia, the earliest Western accounts of gunpowder appear in texts written by English philosopher Roger Bacon in the 13th century. The most ardent protagonists were Nathaniel Halhad, Johann Backmann, Quintin Craufurd, however, due to lack of sufficient proof, these theories have not been widely accepted. A major problem confronting the study of the history of gunpowder is ready access to sources close to the events described. The translation difficulty has led to errors or loose interpretations bordering on artistic licence, early writings potentially mentioning gunpowder are sometimes marked by a linguistic process where old words acquired new meanings. For instance, the Arabic word naft transitioned from denoting naphtha to denoting gunpowder, saltpeter was known to the Chinese by the mid-1st century AD and there is strong evidence of the use of saltpeter and sulfur in various largely medicinal combinations

Smokeless powder
–
Smokeless powder is the name given to a number of propellants used in firearms and artillery that produce negligible smoke when fired, unlike the black powder they replaced. The basis of the term smokeless is that the products are mainly gaseous. Despite its name, smokeless powder is not completely free of smoke, while there may be little noticeable smoke from small-arms ammunition, since the 14th century gunpowder was not actually a physical powder, and smokeless powder can be produced only as a pelletized or extruded granular material. Smokeless powder allowed the development of modern semi- and fully automatic firearms and lighter breeches, burnt black powder leaves a thick, heavy fouling that is hygroscopic and causes rusting of the barrel. The fouling left by smokeless powder exhibits none of these properties and this makes an autoloading firearm with many moving parts feasible. However, they are used as propellants, in normal use. Before the widespread introduction of smokeless powder the use of black powder caused many problems on the battlefield, Military commanders since the Napoleonic Wars reported difficulty with giving orders on a battlefield obscured by the smoke of firing. Verbal commands could not be heard above the noise of the guns, unless there was a strong wind, after a few shots, soldiers using black powder ammunition would have their view obscured by a huge cloud of smoke. Snipers or other concealed shooters were given away by a cloud of smoke over the firing position, black powder is also corrosive, making cleaning mandatory after every use. Likewise, black powders tendency to produce severe fouling caused actions to jam, nitroglycerine was synthesized by the Italian chemist Ascanio Sobrero in 1847. Nitroglycerine is also sensitive, making it unfit to be carried in battlefield conditions. A major step forward was the discovery of guncotton, a nitrocellulose-based material and he promoted its use as a blasting explosive and sold manufacturing rights to the Austrian Empire. Guncotton was more powerful than gunpowder, but at the time was once again somewhat more unstable. John Taylor obtained an English patent for guncotton, and John Hall & Sons began manufacture in Faversham, English interest languished after an explosion destroyed the Faversham factory in 1847. Small arms could not withstand the pressures generated by guncotton, Abel patented this process in 1865 when the second Austrian guncotton factory exploded. After the Stowmarket factory exploded in 1871, Waltham Abbey began production of guncotton for torpedo, in 1863, Prussian artillery captain Johann F. E. Schultze patented a small-arms propellent of nitrated hardwood impregnated with saltpeter or barium nitrate. Prentice received an 1866 patent for a powder of nitrated paper manufactured at Stowmarket. In 1871, Frederick Volkmann received an Austrian patent for a version of Schultze powder called Collodin

Commonwealth of Nations
–
The Commonwealth of Nations, also known as simply the Commonwealth, is an intergovernmental organisation of 52 member states that are mostly former territories of the British Empire. The Commonwealth dates back to the century with the decolonisation of the British Empire through increased self-governance of its territories. It was formally constituted by the London Declaration in 1949, which established the states as free. The symbol of free association is Queen Elizabeth II who is the Head of the Commonwealth. The Queen is also the monarch of 16 members of the Commonwealth, the other Commonwealth members have different heads of state,31 members are republics and five are monarchies with a different monarch. Member states have no obligation to one another. Instead, they are united by language, history, culture and their values of democracy, free speech, human rights. These values are enshrined in the Commonwealth Charter and promoted by the quadrennial Commonwealth Games, the Commonwealth covers more than 29,958,050 km2, 20% of the worlds land area, and spans all six inhabited continents. She declared, So, it marks the beginning of that free association of independent states which is now known as the Commonwealth of Nations. As long ago as 1884, however, Lord Rosebery, while visiting Australia, had described the changing British Empire—as some of its colonies became more independent—as a Commonwealth of Nations. Conferences of British and colonial prime ministers occurred periodically from the first one in 1887, the Commonwealth developed from the imperial conferences. Newfoundland never did, as on 16 February 1934, with the consent of its parliament, Newfoundland later joined Canada as its 10th province in 1949. Australia and New Zealand ratified the Statute in 1942 and 1947 respectively, after World War II ended, the British Empire was gradually dismantled. Most of its components have become independent countries, whether Commonwealth realms or republics, there remain the 14 British overseas territories still held by the United Kingdom. In April 1949, following the London Declaration, the word British was dropped from the title of the Commonwealth to reflect its changing nature, burma and Aden are the only states that were British colonies at the time of the war not to have joined the Commonwealth upon independence. Hoped for success was reinforced by such achievements as climbing Mount Everest in 1953, breaking the four minute mile in 1954, however, the humiliation of the Suez Crisis of 1956 badly hurt morale of Britain and the Commonwealth as a whole. More broadly, there was the loss of a role of the British Empire. That role was no longer militarily or financially feasible, as Britains withdrawal from Greece in 1947 painfully demonstrated, Britain itself was now just one part of the NATO military alliance in which the Commonwealth had no role apart from Canada

Litre
–
The litre or liter is an SI accepted metric system unit of volume equal to 1 cubic decimetre,1,000 cubic centimetres or 1/1,000 cubic metre. A cubic decimetre occupies a volume of 10×10×10 centimetres and is equal to one-thousandth of a cubic metre. The original French metric system used the litre as a base unit. The word litre is derived from an older French unit, the litron, whose name came from Greek — where it was a unit of weight, not volume — via Latin, and which equalled approximately 0.831 litres. The litre was also used in subsequent versions of the metric system and is accepted for use with the SI. The spelling used by the International Bureau of Weights and Measures is litre, the less common spelling of liter is more predominantly used in American English. One litre of water has a mass of almost exactly one kilogram. Subsequent redefinitions of the metre and kilogram mean that this relationship is no longer exact, a litre is defined as a special name for a cubic decimetre or 10 centimetres ×10 centimetres ×10 centimetres. Hence 1 L ≡0.001 m3 ≡1000 cm3, from 1901 to 1964, the litre was defined as the volume of one kilogram of pure water at maximum density and standard pressure. The kilogram was in turn specified as the mass of a platinum/iridium cylinder held at Sèvres in France and was intended to be of the mass as the 1 litre of water referred to above. It was subsequently discovered that the cylinder was around 28 parts per million too large and thus, during this time, additionally, the mass-volume relationship of water depends on temperature, pressure, purity and isotopic uniformity. In 1964, the definition relating the litre to mass was abandoned in favour of the current one, although the litre is not an official SI unit, it is accepted by the CGPM for use with the SI. CGPM defines the litre and its acceptable symbols, a litre is equal in volume to the millistere, an obsolete non-SI metric unit customarily used for dry measure. The litre is often used in some calculated measurements, such as density. One litre of water has a mass of almost exactly one kilogram when measured at its maximal density, similarly,1 millilitre of water has a mass of about 1 g,1,000 litres of water has a mass of about 1,000 kg. It is now known that density of water depends on the isotopic ratios of the oxygen and hydrogen atoms in a particular sample. The litre, though not an official SI unit, may be used with SI prefixes, the most commonly used derived unit is the millilitre, defined as one-thousandth of a litre, and also often referred to by the SI derived unit name cubic centimetre. It is a commonly used measure, especially in medicine and cooking, Other units may be found in the table below, where the more often used terms are in bold

Bolt action
–
Bolt-action firearms are most often rifles, but there are some bolt-action shotguns and a few handguns as well. Examples of this date as far back as the early 19th century. From the late 19th century, all the way through both World Wars, the rifle was the standard infantry firearm for most of the worlds militaries. Bolt-action firearms are still popular for hunting and target shooting. The first bolt-action rifle was produced in 1824 by Johann Nikolaus von Dreyse, von Dreyse would perfect his Nadelgewehr by 1836, and it was adopted by the Prussian Army in 1841. It however was not the first bolt-action weapon to see combat as it was not fielded until 1864, during the American Civil War, the bolt-action Palmer carbine was patented in 1863, and by 1865,1000 were purchased for use as cavalry weapons. The French Army adopted its first bolt-action rifle, the Chassepot rifle, in 1866, ultimately the military turned to bolt-action rifles using a box magazine, the first of its kind was the M1885 Remington–Lee, but the first to be generally adopted was the British 1888 Lee–Metford. World War I marked the height of the bolt-action rifles use, there are, however, many semi-automatic sniper rifle designs, especially in the designated marksman role. Today, bolt-action rifles are used as hunting rifles. These rifles can be used to hunt anything from vermin, to deer, to game, especially big game caught on a safari. Bolt-action shotguns are considered a rarity among modern firearms, but were formerly a commonly used action for.410 entry-level shotguns, as well as for low-cost 12 gauge shotguns. The M26 Modular Accessory Shotgun System is the most advanced and recent example of a bolt-action shotgun, some pistols utilize a bolt action, although this is uncommon, and such examples are typically specialized target handguns. Most of the bolt-action designs involve the shooters doing a turn + pull handle movement to open the bolt, cock the firing pin, there are three major turning bolt-action system designs, the Mauser system, the Lee–Enfield system, and the Mosin–Nagant system. The vast majority of bolt-action rifles utilize one of three systems, with other designs seeing only limited use. The Mauser system is stronger than that of the Lee–Enfield due to two locking lugs just behind the head which make it better able to handle higher pressure cartridges. The 8×68mm S and 9. 3×64mm Brenneke magnum rifle cartridge families were designed for the Mauser M98 bolt action. A novel safety feature was the introduction of a locking lug present at the rear of the bolt that normally did not lock the bolt. The Mauser system features cock on opening, meaning the upward rotation of the bolt when the rifle is opened cocks the action, a drawback of the Mauser M98 system is that it cannot be cheaply mass-produced very easily

Machine gun
–
A machine gun is a fully automatic mounted or portable firearm designed to fire bullets in quick succession from an ammunition belt or magazine, typically at a rate of 300 to 1800 rounds per minute. Note that not all fully automatic firearms are machine guns, submachine guns, rifles, assault rifles, shotguns, pistols or cannons may be capable of fully automatic fire, but are not designed for sustained fire. Many machine guns also use belt feeding and open bolt operation, unlike semi-automatic firearms, which require one trigger pull per round fired, a machine gun is designed to fire for as long as the trigger is held down. Nowadays the term is restricted to heavy weapons, able to provide continuous or frequent bursts of automatic fire for as long as ammunition lasts. Machine guns are used against personnel, aircraft and light vehicles, or to provide suppressive fire. Some machine guns have in practice sustained fire almost continuously for hours, because they become very hot, practically all machine guns fire from an open bolt, to permit air cooling from the breech between bursts. They also usually have either a barrel cooling system, slow-heating heavyweight barrel, although subdivided into light, medium, heavy or general-purpose, even the lightest machine guns tend to be substantially larger and heavier than standard infantry arms. Medium and heavy guns are either mounted on a tripod or on a vehicle, when carried on foot. Medium machine guns use full-sized rifle rounds and are designed to be used from fixed positions mounted on a tripod. 50in, the M249 automatic rifle is operated by an automatic rifleman, but its ammunition may be carried by other Soldiers within the squad or unit. The M249 machine gun is a crew-served weapon, Machine guns usually have simple iron sights, though the use of optics is becoming more common. Many heavy machine guns, such as the Browning M2.50 caliber machine gun, are enough to engage targets at great distances. During the Vietnam War, Carlos Hathcock set the record for a shot at 7382 ft with a.50 caliber heavy machine gun he had equipped with a telescopic sight. This led to the introduction of.50 caliber anti-materiel sniper rifles, selective fire rifles firing a full-power rifle cartridge from a closed bolt are called automatic rifles or battle rifles, while rifles that fire an intermediate cartridge are called assault rifles. Unlocking and removing the spent case from the chamber and ejecting it out of the weapon as bolt is moving rearward Loading the next round into the firing chamber. Usually the recoil spring tension pushes bolt back into battery and a cam strips the new round from a feeding device, cycle is repeated as long as the trigger is activated by operator. Releasing the trigger resets the trigger mechanism by engaging a sear so the weapon stops firing with bolt carrier fully at the rear, the operation is basically the same for all autoloading firearms, regardless of the means of activating these mechanisms. Most modern machine guns use gas-operated reloading, a recoil actuated machine gun uses the recoil to first unlock and then operate the action. Machine guns such as the M2 Browning and MG42, are of this type, a cam, lever or actuator demultiplicates the energy of the recoil to operate the bolt

Percussion cap
–
The percussion cap, introduced circa 1820, was the crucial invention that enabled muzzleloading firearms to fire reliably in any weather. This gave rise to the caplock or percussionlock system, before this development, firearms used flintlock ignition systems that produced flint-on-steel sparks to ignite a pan of priming powder and thereby fire the guns main powder charge. Flintlocks were prone to misfire in wet weather, and many flintlock firearms were later converted to the more reliable percussion system, the percussion cap is a small cylinder of copper or brass with one closed end. Inside the closed end is an amount of a shock-sensitive explosive material such as fulminate of mercury. The percussion cap is placed over a hollow metal nipple at the end of the gun barrel. Pulling the trigger releases a hammer strikes the percussion cap. The flame travels through the nipple to ignite the main powder charge. Percussion caps were, and still are, made in sizes for pistols and larger sizes for rifles. While the metal percussion cap was the most popular and widely used type of primer, accordingly, several manufacturers developed alternative, auto-priming systems. The Maynard tape primer, for example, used a roll of paper much like todays toy cap gun. The Maynard tape primer was fitted to some firearms used in the mid-nineteenth century, other disc or pellet-type primers held a supply of tiny fulminate detonator discs in a small magazine. Cocking the hammer automatically advanced a disc into position, however, these automatic feed systems were difficult to make with the manufacturing systems in the early and mid-nineteenth century and generated more problems than they solved. While it had a number of problems, it was used by the Prussians. In the 1850s, the cap was first integrated into a metallic cartridge. By the late 1860s, breech-loading metallic cartridges had made the percussion cap system obsolete, today, reproduction percussion firearms are popular for recreational shooters and percussion caps are still available. Most percussion caps now use non-corrosive compounds such as lead styphnate, the percussion cap replaced the flint, the steel frizzen, and the powder pan of the flint-lock mechanism. It was only applied to the British military musket in 1842. The first percussion firearm produced for the US military was the carbine version of the M1819 Hall rifle

Proof test
–
A proof test is a form of stress test to demonstrate the fitness of a load-bearing structure, or rescue strop. An individual proof test may apply only to the unit tested, such a structure is often subjected to loads above that expected in actual use, demonstrating safety and design margin. Proof testing is nominally a nondestructive test, particularly if both design margins and test levels are well-chosen, however, unit failures are by definition considered to have been destroyed for their originally-intended use and load levels. Proof tests may be performed before a new design or unit is allowed to service, or perform additional uses. Cranes and derricks are proof tested when called on for potentially dangerous load levels or high-valued cargoes, similarly, items which are smaller and more common are nevertheless in the load path and a failure risk if not tested. Testing generally involves lifting weight or drawing tension equal to or greater than design levels, an overspeed proof test involves physically running the machine at high speed up to the test speed. This may be done during manufacture as a proof test. Physical overspeed tests may be undertaken on some machines to verify operation of the overspeed protection systems. Operation at speeds above the operating speed can greatly increase stress levels in rotating parts. Failing flywheels, rotors, etc. may present a risk in case of a failure. Historically, swords would be tested by impact before issuance- the British test. Vessels which may be a risk, such as utility-scale water towers, chemical-handling equipment, or very-high-pressure storage tanks. Rocket stage tankage, being high-valued and often the primary structure, are proof-tested when redesigned. Testing involves exposure to higher pressures than design levels, or in some cases. A firearms chamber and barrel become pressure vessels for brief periods, in firearm terminology, a proof test is a test wherein a deliberately over-pressured round is fired from a firearm in order to verify that the firearm is not defective and will not explode on firing. The firearm is inspected after the test, and if it is found to be in sound condition, in many jurisdictions a proof test and valid proof mark are required for the sale of firearms. A proof round is an assembly designed to be used in proof testing, this can use a fixed cartridge. A proof shot is a special projectile used in a round or other projectile weapons

Bolt thrust
–
The applied force has both magnitude and direction, making it a vector quantity. Bolt thrust is an important factor in weapons design, the greater the bolt thrust, the stronger the locking mechanism has to be to withstand it. Assuming equal engineering solutions and material adding strength to a locking mechanism causes an increase in weight, bolt thrust is not a measure to determine the amount of recoil/free recoil. With a basic calculation the bolt thrust produced by a firearms cartridge can be calculated fairly accurately. F → b o l t = P m a x ⋅ A i n t e r n a l, the area enclosed by a circle is, A r e a = π r 2 ≈3. Where, π ≈3.1416 r = the radius of the circle Equivalently, a practical problem regarding this method is that the internal case head diameter of a particular production lot of cartridge cases can not be easily measured without damaging them. A complicating matter regarding bolt thrust is that a cartridge case expands and deforms under high pressure and this friction-effect can be accounted for with finite elements calculations on a computer, but it is a lot of specialized work and generally not worth the trouble. By oiling proof rounds during NATO EPVAT testing procedures, NATO test centers intentionally lower case friction to promote high bolt thrust levels. The basic calculation method is almost the same, but now the larger area of the cartridge case head is used instead of the smaller inside area.
