Kingdom of Romania
–
The Kingdom of Romania was a constitutional monarchy which existed between 13 March 1881 and 30 December 1947, specified by the first three Constitutions of Romania. As such, it is distinct from the Romanian Old Kingdom. From 1859 to 1877, Romania evolved from a union of two vassal principalities under a single prince to a full-fledged independent kingdom with a Hohenzollern monarchy. During 1918-20, at the end of World War I, Transylvania, Eastern Moldavia, in 1947 King Michael was compelled to abdicate and a socialist republic ruled by the Romanian Communist Party replaced the monarchy. The 1859 ascendancy of Alexandru Ioan Cuza as prince of both Moldavia and Wallachia under the suzerainty of the Ottoman Empire united an identifiably Romanian nation under a single ruler. On 5 February 1862 the two principalities were united to form the Principality of Romania, with Bucharest as its capital. On 23 February 1866 a so-called Monstrous coalition, composed of Conservatives and radical Liberals, the German prince Charles of Hohenzollern-Sigmaringen was appointed as Prince of Romania, in a move to assure German backing to unity and future independence. He immediately adopted the Romanian spelling of his name, Carol, on 15 March 1881, as an assertion of full sovereignty, the Romanian parliament raised the country to the status of a kingdom, and Carol was crowned as king on 10 May. Abstaining from the Initial Balkan War against the Ottoman Empire, the Kingdom of Romania entered the Second Balkan War in June 1913 against the Tsardom of Bulgaria,330,000 Romanian troops moved across the Danube and into Bulgaria. One army occupied Southern Dobrudja and another moved into northern Bulgaria to threaten Sofia, Romania thus acquired the ethnically-mixed territory of Southern Dobrudja, which it had desired for years. In 1916 Romania entered World War I on the Entente side, the term came into use after World War I, when the Old Kingdom was opposed to Greater Romania, which included Transylvania, Banat, Bessarabia, and Bukovina. Nowadays, the term mainly has a historical relevance, and is used as a common term for all regions in Romania included in both the Old Kingdom and present-day borders. Romania delayed in entering World War I, but ultimately declared war on the Central Powers in 1916, War with the Hungarian Soviet Republic in 1919 resulted in the occupation of Budapest by Romanian troops and the end of Béla Kuns Bolshevik regime. At the Paris Peace Conference, Romania received territories of Transylvania, part of Banat, Bessarabia, thus, Romania in 1920 was more than twice the size it had been in 1914. Although the country was satisfied and had no territorial claims, it aroused the enmity of Bulgaria, and especially Hungary. Greater Romania now encompassed a significant minority population, especially of Hungarians, by contrast, the prewar Romanian state had only one real minority, Jews, but nonetheless anti-Semitism was widespread. Transylvania had significant Hungarian and German population, and with a contemptuous attitude towards Romanians. Both groups were excluded from politics as the postwar Romanian regime passed an edict stating that all personnel employed by the state had to speak Romanian

Howitzer
–
In the taxonomies of artillery pieces used by European armies in the 17th to 20th centuries, the howitzer stood between the gun and the mortar. Howitzers, like other artillery equipment, are organized in groups called batteries. The English word howitzer comes from the Czech word houfnice, from houf, crowd, haufen, sometimes in the compound Gewalthaufen, also designated a pike square formation in German. This is particularly true in the forces of the United States. Because of this practice, the howitzer is used in some armies as a generic term for any kind of artillery piece that is designed to attack targets using indirect fire. Thus, artillery pieces that bear resemblance to howitzers of earlier eras are now described as howitzers. Most other armies in the reserve the word howitzer for guns with barrel lengths 15 to 25 times their caliber. The British had a method of nomenclature. In the 18th century, they adopted projectile weight for guns replacing the old naming system of culverin, saker, mortars had been categorized by calibre in inches in the 17th century and this was inherited by howitzers. The modern howitzers were invented in Sweden towards the end of the 17th century, originally intended for use in siege warfare, they were particularly useful for delivering cast-iron shells filled with gunpowder or incendiary materials into the interior of fortifications. In the middle of the 18th century, a number of European armies began to introduce howitzers that were enough to accompany armies in the field. Though usually fired at the high angles of fire used by contemporary siege howitzers. Rather, as the guns of the day were usually restricted to inert projectiles. Many, for the sake of simplicity and rapidity of fire, the Abus gun was an early form of howitzer in the Ottoman Empire. In 1758 the Russian Empire introduced a type of howitzer, with a conical chamber, called a licorne. The most famous of these gun-howitzers was the Napoleon 12-pounder, a weapon of French design that saw service in the American Civil War. The longest-serving artillery piece of the 19th century was the mountain howitzer, in 1859, the armies of Europe began to rearm field batteries with rifled field guns. These new field pieces used cylindrical projectiles that, while smaller in caliber than the spherical shells of smoothbore field howitzers, moreover, their greater range let them create many of the same effects that previously required the sharply curved trajectories of smoothbore field howitzers

Second Balkan War
–
Serbian and Greek armies repulsed the Bulgarian offensive and counter-attacked, entering Bulgaria. With Bulgaria also having engaged in territorial disputes with Romania. The Ottoman Empire also took advantage of the situation to some lost territories from the previous war. In the Treaty of Constantinople, it lost Edirne to the Ottomans, the political developments and military preparations for the Second Balkan War attracted an estimated 200–300 war correspondents from around the world. During the First Balkan War, the Balkan League succeeded in driving out the Ottoman Empire from its European provinces, leaving the Ottomans with only the Çatalca, however, the relations between the victorious Balkan allies quickly soured over the division of the spoils, especially in Macedonia. In the event, during the war, the Serbs succeeded in capturing an area far south of the agreed border, at the same time, the Greeks advanced north, occupying Thessaloniki shortly before the Bulgarians arrived, and establishing a common Greek border with Serbia. The developments essentially ended the Serbo-Bulgarian alliance and made a war between the two countries inevitable. Soon thereafter, minor clashes broke out along the borders of the zones with the Bulgarians against the Serbs. Responding to the perceived Bulgarian threat, Serbia started negotiations with Greece, with this agreement, Serbia succeeded in making Greece a part of its dispute over northern Macedonia, since Greece had guaranteed Serbias current occupation zone in Macedonia. However, his later dismissal put an end to the targeting of Serbia. Another point of friction arose, Bulgarias refusal to cede the fortress of Silistra to Romania, Romania threatened to occupy Bulgarian territory by force, but a Russian proposal for arbitration prevented hostilities. In the resulting Protocol of St. Petersburg of 8 May 1913, the resulting agreement was a compromise between the Romanian demands for the entire southern Dobruja and the Bulgarian refusal to accept any cession of its territory. However the fact that Russia failed to protect the integrity of Bulgaria made the Bulgarians uncertain of the reliability of the expected Russian arbitration of the dispute with Serbia. The Bulgarian behavior had also an impact on the Russo-Bulgarian relations. Both acts made conflict with Romania and Serbia inevitable, by mid-June Bulgaria became aware of the agreement between Serbia and Greece in case of a Bulgarian attack. On 27 June Montenegro announced that it would side with Serbia in the event of a Serbian-Bulgarian war, on 8 June, he sent an identical personal message to the Kings of Bulgaria and Serbia, offering to act as arbitrator according to the provisions of the 1912 Serbo-Bulgarian treaty. That caused Russia to cancel the initiative and to angrily repudiate its 1902 treaty of alliance with Bulgaria. Then Serbia and Greece proposed that each of the three countries reduce its army by one fourth, as a first step to facilitate a peaceful solution, but Bulgaria rejected it

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

Gun barrel
–
A gun barrel is a part of firearms and artillery pieces. The hollow interior of the barrel is called the bore, a gun barrel must be able to hold in the expanding gas produced by the propellants to ensure that optimum muzzle velocity is attained by the projectile as it is being pushed out by the expanding gas. Modern small arms barrels are made of known and tested to withstand the pressures involved. Artillery pieces are made by various techniques providing reliably sufficient strength, early firearms were muzzle-loading, with powder, and then shot loaded from the muzzle, capable of only a low rate of fire. During the 19th century effective mechanical locks were invented that sealed a breech-loading weapon against the escape of propellant gases, the early Chinese, the inventors of gunpowder, used bamboo, a naturally tubular stalk, as the first barrels in gunpowder projectile weapons. Early European guns were made of iron, usually with several strengthening bands of the metal wrapped around circular wrought iron rings. The Chinese were the first to master cast-iron cannon barrels, early cannon barrels were very thick for their caliber.

Shell (projectile)
–
A shell is a payload-carrying projectile that, as opposed to shot, contains an explosive or other filling, though modern usage sometimes includes large solid projectiles properly termed shot. Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used, originally, it was called a bombshell, but shell has come to be unambiguous in a military context. Words cognate with grenade are still used for an artillery or mortar projectile in some European languages, shells are usually large-calibre projectiles fired by artillery, combat vehicles, and warships. Shells usually have the shape of a cylinder topped by a nose for good aerodynamic performance, possibly with a tapering base. Solid cannonballs did not need a fuse, but hollow munitions filled with something such as gunpowder to fragment the ball, needed a fuse, percussion fuses with a spherical projectile presented a challenge because there was no way of ensuring that the impact mechanism hit the target. Therefore, shells needed a fuse that was ignited before or during firing. The earliest record of shells being used in combat was by the Republic of Venice at Jadra in 1376, shells with fuses were used at the 1421 siege of St Boniface in Corsica. These were two hollowed hemispheres of stone or bronze held together by an iron hoop, as described in their book, these hollow, gunpowder-packed shells were made of cast iron. At least since the 16th Century grenades made of ceramics or glass were in use in Central Europe, a hoard of several hundred ceramic greandes were discovered during building works in front of a bastion of the Bavarian City of Ingolstadt, Germany dated to the 17th Century. Lots of the grenades obtained their orignal blackpowder loads and igniters, most probably the grenades were intentionally dumped the moat of the bastion before the year 1723. Early powder burning fuses had to be loaded fuse down to be ignited by firing or a portfire put down the barrel to light the fuse, other shells were wrapped in bitumen cloth, which would ignite during the firing and in turn ignite a powder fuse. Nevertheless, shells came into use in the 16th Century. By the 18th Century, it was known that the fuse towards the muzzle could be lit by the flash through the windage between the shell and the barrel, the use of exploding shells from field artillery became relatively commonplace from early in the 19th century. Until the mid 19th century, shells remained as simple exploding spheres that used gunpowder and they were usually made of cast iron, but bronze, lead, brass and even glass shell casings were experimented with. The word bomb encompassed them at the time, as heard in the lyrics of The Star-Spangled Banner, typically, the thickness of the metal body was about a sixth of their diameter and they were about two thirds the weight of solid shot of the same calibre. To ensure that shells were loaded with their fuses towards the muzzle, in 1819, a committee of British artillery officers recognised that they were essential stores and in 1830 Britain standardised sabot thickness as a half inch. The sabot was also intended to reduce jamming during loading, despite the use of exploding shell, the use of smoothbore cannons, firing spherical projectiles of shot, remained the dominant artillery method until the 1850s. By the late 18th century, artillery could use canister shot to defend itself from infantry or cavalry attack and this involved loading a tin or canvas container filled with small iron or lead balls instead of the usual cannonball

Gun carriage
–
A gun carriage is a frame and mount that supports the gun barrel of an artillery piece, allowing it to be manoeuvred and fired. The earliest guns were laid directly onto the ground, with earth being piled up under the end of the barrel to increase the elevation. As the size of guns increased, they began to be attached to wooden frames or beds that were held down by stakes. These began to be replaced by wheeled carriages in the early 16th century, from the 16th to the mid-19th century, the main form of artillery remained the smoothbore cannon. By this time, the trunnion had been developed, with the result that the barrel could be held in two recesses in the carriage and secured with an iron band. This simplified elevation, which was achieved by raising or lowering the breech of the gun by means of a wedge called a quoin or later by a steel screw. During this time, the design of gun carriages evolved only slowly, the trunnions of the gun barrel sat on the top of the cheeks, the rearward part of each cheek was stepped so that the breech could be lifted by iron levers called handspikes. Traversing the gun was achieved by levering the rear of the carriage sideways with handspikes and these were designed to allow guns to be deployed on the battlefield and were provided with a pair of large wheels similar to those used on carts or wagons. The cheeks of field carriages were much narrower than those on the naval carriage, when the gun needed to be moved any distance, the trail could be lifted onto a second separate axle called a limber, which could then be towed by a team of horses or oxen. Limbers had been invented in France in about 1550, in recent times, most heavy guns in military service, that were not themselves mounted into a vehicles, have been mounted either with a field carriage or a split trail carriage. The field carriage is simpler - having two legs extend backwards, joining at a tail, being a hardpoint to hook on to a prime mover or set of horses, the split trail carriage, however, is more complicated, but offers distinct advantages. It consists of two legs, able to be spread independently to the sides, or brought together to allow towing or movement, in both cases, the tail of the carriage often serves to balance the gun, and protect it from rolling to any large extent. The split trail, however, allows the gun not only to be fired near the horizontal, as the field carriage does and this is less important for heavier artillery, as the guns already involve a long time to prepare a firing position. While this still limits the ability to track, it allows the guns to fire in any direction with minimal preparation. Furthermore, it part of each of the benefits of the field carriage, being weight, space. The practice has its origins in war and appears in the century in the Queens regulations of the British Army. In the United Kingdom, the visual distinction usually referred to is that in a state funeral and this distinguishing feature is not invariable, however, as shown by the use of naval ratings rather than horses at the ceremonial funeral for Lord Mountbatten in 1979

Gun laying
–
Gun laying is the process of aiming an artillery piece, such as a gun, howitzer or mortar on land, or at sea, against surface or air targets. It may be laying for direct fire, where the gun is aimed similarly to a rifle, or indirect fire, the term includes automated aiming using, for example, radar-derived target data and computer-controlled guns. Gun laying means moving the axis of the bore of the barrel in two planes, horizontal and vertical. A gun is traversed – rotated in a horizontal plane – to align it with the target, Gun laying is a set of actions to align the axis of a gun barrel so that it points in the required direction. This alignment is in the horizontal and vertical planes, Gun laying may be for direct fire, where the layer sees the target, or indirect fire, where the target may not be visible from the gun. Gun laying has sometimes called training the gun. Laying in the vertical plane uses data derived from trials or empirical experience, for any given gun and projectile types, it reflects the distance to the target and the size of the propellant charge. It also incorporates any differences in height between gun and target, with indirect fire, it may allow for other variables as well. With indirect fire the horizontal angle is relative to something, typically the guns aiming point, depending on the gun mount, there is usually a choice of two trajectories. The dividing angle between the trajectories is about 45 degrees, it varies due to gun dependent factors. Below 45 degrees the trajectory is called low angle, above is high angle, the differences are that low angle fire has a shorter time of flight, a lower vertex and flatter angle of descent. All guns have carriages or mountings that support the barrel assembly, early guns could only be traversed by moving their entire carriage or mounting, and this lasted with heavy artillery into World War II. Mountings could be fitted into traversing turrets on ships, coast defences or tanks, from circa 1900 field artillery carriages provided traverse without moving the wheels and trail. The carriage, or mounting, also enabled the barrel to be set at the elevation angle. With some gun mounts it is possible to depress the gun, some guns require a near-horizontal elevation for loading. An essential capability for any elevation mechanism is to prevent the weight of the barrel forcing its heavier end downward and this is greatly helped by having trunnions at the centre of gravity, although a counterbalance mechanism can be used. It also means the elevation gear has to be enough to resist considerable downward pressure. However, mortars, where the forces were transferred directly into the ground

Bucharest
–
Bucharest is the capital and largest city of Romania, as well as its cultural, industrial, and financial centre. It is located in the southeast of the country, at 44°25′57″N 26°06′14″E, on the banks of the Dâmbovița River, less than 60 km north of the Danube River, Bucharest was first mentioned in documents in 1459. It became the capital of Romania in 1862 and is the centre of Romanian media, culture and its architecture is a mix of historical, interbellum, communist-era and modern. In the period between the two World Wars, the citys elegant architecture and the sophistication of its elite earned Bucharest the nickname of Little Paris. Although buildings and districts in the city centre were heavily damaged or destroyed by war, earthquakes. In recent years, the city has been experiencing an economic, in 2016, the historical city centre was listed as endangered by the World Monuments Watch. According to the 2011 census,1,883,425 inhabitants live within the city limits, the urban area extends beyond the limits of Bucharest proper and has a population of about 1.9 million people. Adding the satellite towns around the area, the proposed metropolitan area of Bucharest would have a population of 2.27 million people. According to Eurostat, Bucharest has an urban zone of 2,183,091 residents. According to unofficial data, the population is more than 3 million, Bucharest is the sixth-largest city in the European Union by population within city limits, after London, Berlin, Madrid, Rome, and Paris. Economically, Bucharest is the most prosperous city in Romania and is one of the industrial centres. The city has big convention facilities, educational institutes, cultural venues, traditional shopping arcades, the Romanian name București has an uncertain origin. Tradition connects the founding of Bucharest with the name of Bucur, who was a prince, an outlaw, a fisherman, in Romanian, the word stem bucurie means joy, and it is believed to be of Dacian origin. Other etymologies are given by scholars, including the one of an Ottoman traveler, Evliya Çelebi. A native or resident of Bucharest is called a Bucharester, Bucharests history alternated periods of development and decline from the early settlements in antiquity until its consolidation as the national capital of Romania late in the 19th century. First mentioned as the Citadel of București in 1459, it became the residence of the famous Wallachian prince Vlad III the Impaler, the Ottomans appointed Greek administrators to run the town from the 18th century. A short-lived revolt initiated by Tudor Vladimirescu in 1821 led to the end of the rule of Constantinople Greeks in Bucharest, the Old Princely Court was erected by Mircea Ciobanul in the mid-16th century. Under subsequent rulers, Bucharest was established as the residence of the royal court

Artillery
–
Artillery is a class of large military weapons built to fire munitions far beyond the range and power of infantrys small arms. Early artillery development focused on the ability to breach fortifications, and led to heavy, as technology improved, lighter, more mobile field artillery developed for battlefield use. This development continues today, modern self-propelled artillery vehicles are highly mobile weapons of great versatility providing the largest share of an armys total firepower, in its earliest sense, the word artillery referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. In common speech, the artillery is often used to refer to individual devices, along with their accessories and fittings. However, there is no generally recognised generic term for a gun, howitzer, mortar, and so forth, the United States uses artillery piece, the projectiles fired are typically either shot or shell. Shell is a widely used term for a projectile, which is a component of munitions. By association, artillery may also refer to the arm of service that customarily operates such engines, in the 20th Century technology based target acquisition devices, such as radar, and systems, such as sound ranging and flash spotting, emerged to acquire targets, primarily for artillery. These are usually operated by one or more of the artillery arms, Artillery originated for use against ground targets—against infantry, cavalry and other artillery. An early specialist development was coastal artillery for use against enemy ships, the early 20th Century saw the development of a new class of artillery for use against aircraft, anti-aircraft guns. Artillery is arguably the most lethal form of land-based armament currently employed, the majority of combat deaths in the Napoleonic Wars, World War I, and World War II were caused by artillery. In 1944, Joseph Stalin said in a speech that artillery was the God of War, although not called as such, machines performing the role recognizable as artillery have been employed in warfare since antiquity. The first references in the historical tradition begin at Syracuse in 399 BC. From the Middle Ages through most of the era, artillery pieces on land were moved by horse-drawn gun carriages. In the contemporary era, the artillery and crew rely on wheeled or tracked vehicles as transportation, Artillery used by naval forces has changed significantly also, with missiles replacing guns in surface warfare. The engineering designs of the means of delivery have likewise changed significantly over time, in some armies, the weapon of artillery is the projectile, not the equipment that fires it. The process of delivering fire onto the target is called gunnery, the actions involved in operating the piece are collectively called serving the gun by the detachment or gun crew, constituting either direct or indirect artillery fire. The term gunner is used in armed forces for the soldiers and sailors with the primary function of using artillery. The gunners and their guns are usually grouped in teams called either crews or detachments, several such crews and teams with other functions are combined into a unit of artillery, usually called a battery, although sometimes called a company

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
