Pakistan the Islamic Republic of Pakistan, is a country in South Asia. It is the world’s sixth-most populous country with a population exceeding 212,742,631 people. In area, it is the 33rd-largest country. Pakistan has a 1,046-kilometre coastline along the Arabian Sea and Gulf of Oman in the south and is bordered by India to the east, Afghanistan to the west, Iran to the southwest, China in the far northeast, it is separated narrowly from Tajikistan by Afghanistan's Wakhan Corridor in the northwest, shares a maritime border with Oman. The territory that now constitutes Pakistan was the site of several ancient cultures and intertwined with the history of the broader Indian subcontinent; the ancient history involves the Neolithic site of Mehrgarh and the Bronze Age Indus Valley Civilisation, was home to kingdoms ruled by people of different faiths and cultures, including Hindus, Indo-Greeks, Turco-Mongols and Sikhs. The area has been ruled by numerous empires and dynasties, including the Persian Achaemenid Empire, Alexander III of Macedon, the Seleucid Empire, the Indian Maurya Empire, the Gupta Empire, the Arab Umayyad Caliphate, the Delhi Sultanate, the Mongol Empire, the Mughal Empire, the Afghan Durrani Empire, the Sikh Empire and, most the British Empire.
Pakistan is the only country to have been created in the name of Islam. It is an ethnically and linguistically diverse country, with a diverse geography and wildlife. A dominion, Pakistan adopted a constitution in 1956, becoming an Islamic republic. An ethnic civil war and Indian military intervention in 1971 resulted in the secession of East Pakistan as the new country of Bangladesh. In 1973, Pakistan adopted a new constitution which stipulated that all laws are to conform to the injunctions of Islam as laid down in the Quran and Sunnah. A regional and middle power, Pakistan has the sixth-largest standing armed forces in the world and is a nuclear power as well as a declared nuclear-weapons state, the second in South Asia and the only nation in the Muslim world to have that status. Pakistan has a semi-industrialised economy with a well-integrated agriculture sector and a growing services sector, it is ranked among the emerging and growth-leading economies of the world, is backed by one of the world's largest and fastest-growing middle class.
Pakistan's political history since independence has been characterized by periods of military rule, political instability and conflicts with India. The country continues to face challenging problems, including overpopulation, poverty and corruption. Pakistan is a member of the UN, the Shanghai Cooperation Organisation, the OIC, the Commonwealth of Nations, the SAARC and the Islamic Military Counter Terrorism Coalition; the name Pakistan means "land of the pure" in Urdu and Persian. It alludes to the word pāk meaning pure in Pashto; the suffix ـستان is a Persian word meaning the place of, recalls the synonymous Sanskrit word sthāna स्थान. The name of the country was coined in 1933 as Pakstan by Choudhry Rahmat Ali, a Pakistan Movement activist, who published it in his pamphlet Now or Never, using it as an acronym referring to the names of the five northern regions of British India: Punjab, Kashmir and Baluchistan; the letter i was incorporated to ease pronunciation. Some of the earliest ancient human civilisations in South Asia originated from areas encompassing present-day Pakistan.
The earliest known inhabitants in the region were Soanian during the Lower Paleolithic, of whom stone tools have been found in the Soan Valley of Punjab. The Indus region, which covers most of present day Pakistan, was the site of several successive ancient cultures including the Neolithic Mehrgarh and the Bronze Age Indus Valley Civilisation at Harappa and Mohenjo-Daro; the Vedic period was characterised by an Indo-Aryan culture. Multan was an important Hindu pilgrimage centre; the Vedic civilisation flourished in the ancient Gandhāran city of Takṣaśilā, now Taxila in the Punjab, founded around 1000 BCE. Successive ancient empires and kingdoms ruled the region: the Persian Achaemenid Empire, Alexander the Great's empire in 326 BCE and the Maurya Empire, founded by Chandragupta Maurya and extended by Ashoka the Great, until 185 BCE; the Indo-Greek Kingdom founded by Demetrius of Bactria included Gandhara and Punjab and reached its greatest extent under Menander, prospering the Greco-Buddhist culture in the region.
Taxila had one of the earliest universities and centres of higher education in the world, established during the late Vedic period in 6th century BCE. The school consisted of several monasteries without large dormitories or lecture halls where the religious instruction was provided on an individualistic basis; the ancient university was documented by the invading forces of Alexander the Great, "the like of which had not been seen in Greece," and was recorded by Chinese pilgrims in the 4th or 5th century CE. At its zenith, the Rai Dynasty of Sindh ruled the surrounding territories; the Pala Dynasty was the last Buddhist empire, under Dharmapala and Devapala, stretched across South Asia from what is now Bangladesh through Northern India to Pakistan. The Arab conqueror Muhammad bin Qasim conquered Sindh in 711 CE; the Pakistan government's official chronol
Mumbai is the capital city of the Indian state of Maharashtra. As of 2011 it is the most populous city in India with an estimated city proper population of 12.4 million. The larger Mumbai Metropolitan Region is the second most populous metropolitan area in India, with a population of 21.3 million as of 2016. Mumbai has a deep natural harbour. In 2008, Mumbai was named an alpha world city, it is the wealthiest city in India, has the highest number of millionaires and billionaires among all cities in India. Mumbai is home to three UNESCO World Heritage Sites: the Elephanta Caves, Chhatrapati Shivaji Maharaj Terminus, the city's distinctive ensemble of Victorian and Art Deco buildings; the seven islands that constitute Mumbai were home to communities of Koli people, who originated in Gujarat in prehistoric times. For centuries, the islands were under the control of successive indigenous empires before being ceded to the Portuguese Empire and subsequently to the East India Company when in 1661 Charles II of England married Catherine of Braganza and as part of her dowry Charles received the ports of Tangier and Seven Islands of Bombay.
During the mid-18th century, Bombay was reshaped by the Hornby Vellard project, which undertook reclamation of the area between the seven islands from the sea. Along with construction of major roads and railways, the reclamation project, completed in 1845, transformed Bombay into a major seaport on the Arabian Sea. Bombay in the 19th century was characterised by educational development. During the early 20th century it became a strong base for the Indian independence movement. Upon India's independence in 1947 the city was incorporated into Bombay State. In 1960, following the Samyukta Maharashtra Movement, a new state of Maharashtra was created with Bombay as the capital. Mumbai is the financial and entertainment capital of India, it is one of the world's top ten centres of commerce in terms of global financial flow, generating 6.16% of India's GDP and accounting for 25% of industrial output, 70% of maritime trade in India, 70% of capital transactions to India's economy. The city houses important financial institutions such as the Reserve Bank of India, the Bombay Stock Exchange, the National Stock Exchange of India, the SEBI and the corporate headquarters of numerous Indian companies and multinational corporations.
It is home to some of India's premier scientific and nuclear institutes like Bhabha Atomic Research Centre, Nuclear Power Corporation of India, Indian Rare Earths, Tata Institute of Fundamental Research, Atomic Energy Regulatory Board, Atomic Energy Commission of India, the Department of Atomic Energy. The city houses India's Hindi and Marathi cinema industries. Mumbai's business opportunities, as well as its potential to offer a higher standard of living, attract migrants from all over India, making the city a melting pot of many communities and cultures; the name Mumbai is derived from Mumbā or Mahā-Ambā—the name of the patron goddess Mumbadevi of the native Koli community— and ā'ī meaning "mother" in the Marathi language, the mother tongue of the Koli people and the official language of Maharashtra. The Koli people originated in Kathiawad and Central Gujarat, according to some sources they brought their goddess Mumba with them from Kathiawad, where she is still worshipped. However, other sources disagree.
The oldest known names for the city are Galajunkja. In 1508, Portuguese writer Gaspar Correia used the name "Bombaim" in his Lendas da Índia; this name originated as the Galician-Portuguese phrase bom baim, meaning "good little bay", Bombaim is still used in Portuguese. In 1516, Portuguese explorer Duarte Barbosa used the name Tana-Maiambu: Tana appears to refer to the adjoining town of Thane and Maiambu to Mumbadevi. Other variations recorded in the 16th and the 17th centuries include: Mombayn, Bombain, Monbaym, Mombaym, Bombaiim, Boon Bay, Bon Bahia. After the English gained possession of the city in the 17th century, the Portuguese name was anglicised as Bombay. Ali Muhammad Khan, imperial dewan or revenue minister of the Gujarat province, in the Mirat-i Ahmedi referred to the city as Manbai; the French traveller Louis Rousselet who visited in 1863 and 1868 tells us in his book L’Inde des Rajahs: "Etymologists have wrongly derived this name from the Portuguese Bôa Bahia, or, not knowing that the tutelar goddess of this island has been, from remote antiquity, Bomba, or Mamba Dévi, that she still... possesses a temple".
By the late 20th century, the city was referred to as Mumbai or Mambai in Marathi, Gujarati and Sindhi, as Bambai in Hindi. The Government of India changed the English name to Mumbai in November 1995; this came at the insistence of the Marathi nationalist Shiv Sena party, which had just won the Maharashtra state elections, mirrored similar name changes across the country and in Maharashtra. According to Slate magazine, "they argued that'Bombay' was a corrupted English version of'Mumbai' and an unwanted legacy of British colonial rule." Slate said "The push to rename Bombay was part of a larger movement to strengthen Marathi identity in the Maharashtra region." While the city is still referred to as Bombay by some of its residents and by Indians from other regions, mention of the ci
The Royal Navy is the United Kingdom's naval warfare force. Although warships were used by the English kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years War against the Kingdom of France; the modern Royal Navy traces its origins to the early 16th century. From the middle decades of the 17th century, through the 18th century, the Royal Navy vied with the Dutch Navy and with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until surpassed by the United States Navy during the Second World War; the Royal Navy played a key part in establishing the British Empire as the unmatched world power during the 19th and first part of the 20th centuries. Due to this historical prominence, it is common among non-Britons, to refer to it as "the Royal Navy" without qualification. Following World War I, the Royal Navy was reduced in size, although at the onset of World War II it was still the world's largest.
By the end of the war, the United States Navy had emerged as the world's largest. During the Cold War, the Royal Navy transformed into a anti-submarine force, hunting for Soviet submarines and active in the GIUK gap. Following the collapse of the Soviet Union, its focus has returned to expeditionary operations around the world and remains one of the world's foremost blue-water navies. However, 21st century reductions in naval spending have led to a personnel shortage and a reduction in the number of warships; the Royal Navy maintains a fleet of technologically sophisticated ships and submarines including two aircraft carriers, two amphibious transport docks, four ballistic missile submarines, six nuclear fleet submarines, six guided missile destroyers, 13 frigates, 13 mine-countermeasure vessels and 22 patrol vessels. As of November 2018, there are 74 commissioned ships in the Royal Navy, plus 12 ships of the Royal Fleet Auxiliary; the RFA replenishes Royal Navy warships at sea, augments the Royal Navy's amphibious warfare capabilities through its three Bay-class landing ship vessels.
It works as a force multiplier for the Royal Navy doing patrols that frigates used to do. The total displacement of the Royal Navy is 408,750 tonnes; the Royal Navy is part of Her Majesty's Naval Service, which includes the Royal Marines. The professional head of the Naval Service is the First Sea Lord, an admiral and member of the Defence Council of the United Kingdom; the Defence Council delegates management of the Naval Service to the Admiralty Board, chaired by the Secretary of State for Defence. The Royal Navy operates three bases in the United Kingdom; as the seaborne branch of HM Armed Forces, the RN has various roles. As it stands today, the RN has stated its 6 major roles as detailed below in umbrella terms. Preventing Conflict – On a global and regional level Providing Security At Sea – To ensure the stability of international trade at sea International Partnerships – To help cement the relationship with the United Kingdom's allies Maintaining a Readiness To Fight – To protect the United Kingdom's interests across the globe Protecting the Economy – To safe guard vital trade routes to guarantee the United Kingdom's and its allies' economic prosperity at sea Providing Humanitarian Aid – To deliver a fast and effective response to global catastrophes The strength of the fleet of the Kingdom of England was an important element in the kingdom's power in the 10th century.
At one point Aethelred II had an large fleet built by a national levy of one ship for every 310 hides of land, but it is uncertain whether this was a standard or exceptional model for raising fleets. During the period of Danish rule in the 11th century, the authorities maintained a standing fleet by taxation, this continued for a time under the restored English regime of Edward the Confessor, who commanded fleets in person. English naval power declined as a result of the Norman conquest. Following the Battle of Hastings, the Norman navy that brought over William the Conqueror disappeared from records due to William receiving all of those ships from feudal obligations or because of some sort of leasing agreement which lasted only for the duration of the enterprise. More troubling, is the fact that there is no evidence that William adopted or kept the Anglo-Saxon ship mustering system, known as the scipfryd. Hardly noted after 1066, it appears that the Normans let the scipfryd languish so that by 1086, when the Doomsday Book was completed, it had ceased to exist.
According to the Anglo-Saxon Chronicle, in 1068, Harold Godwinson's sons Godwine and Edmund conducted a ‘raiding-ship army’ which came from Ireland, raiding across the region and to the townships of Bristol and Somerset. In the following year of 1069, they returned with a bigger fleet which they sailed up the River Taw before being beaten back by a local earl near Devon. However, this made explicitly clear that the newly conquered England under Norman rule, in effect, ceded the Irish Sea to the Irish, the Vikings of Dublin, other Norwegians. Besides ceding away the Irish Sea, the Normans ceded the North Sea, a major area where Nordic peoples traveled. In 1069, this lack of naval presence in the North Sea allowed for the invasion an
A passenger ship is a merchant ship whose primary function is to carry passengers on the sea. The category does not include cargo vessels which have accommodations for limited numbers of passengers, such as the ubiquitous twelve-passenger freighters once common on the seas in which the transport of passengers is secondary to the carriage of freight; the type does however include many classes of ships designed to transport substantial numbers of passengers as well as freight. Indeed, until virtually all ocean liners were able to transport mail, package freight and express, other cargo in addition to passenger luggage, were equipped with cargo holds and derricks, kingposts, or other cargo-handling gear for that purpose. Only in more recent ocean liners and in all cruise ships has this cargo capacity been eliminated. While passenger ships are part of the merchant marine, passenger ships have been used as troopships and are commissioned as naval ships when used as for that purpose. Passenger ships include ferries, which are vessels for day to day or overnight short-sea trips moving passengers and vehicles.
An ocean liner is the traditional form of passenger ship. Once such liners operated on scheduled line voyages to all inhabited parts of the world. With the advent of airliners transporting passengers and specialized cargo vessels hauling freight, line voyages have died out, but with their decline came an increase in sea trips for pleasure and fun, in the latter part of the 20th century ocean liners gave way to cruise ships as the predominant form of large passenger ship containing from hundreds to thousands of people, with the main area of activity changing from the North Atlantic Ocean to the Caribbean Sea. Although some ships have characteristics of both types, the design priorities of the two forms are different: ocean liners value speed and traditional luxury while cruise ships value amenities rather than speed; these priorities produce different designs. In addition, ocean liners were built to cross the Atlantic Ocean between Europe and the United States or travel further to South America or Asia while cruise ships serve shorter routes with more stops along coastlines or among various islands.
For a long time, cruise ships were smaller than the old ocean liners had been, but in the 1980s, this changed when Knut Kloster, the director of Norwegian Caribbean Lines, bought one of the biggest surviving liners, the SS France, transformed her into a huge cruise ship, which he renamed the SS Norway. Her success demonstrated. Successive classes of ever-larger ships were ordered, until the Cunard liner Queen Elizabeth was dethroned from her 56-year reign as the largest passenger ship built. Both the RMS Queen Elizabeth 2 and her successor as Cunard's flagship RMS Queen Mary 2, which entered service in 2004, are of hybrid construction. Like transatlantic ocean liners, they are fast ships and built to withstand the rigors of the North Atlantic in line voyage service, but both ships are designed to operate as cruise ships, with the amenities expected in that trade. QM2 was superseded by the Freedom of the Seas of the Royal Caribbean line as the largest passenger ship built; the Freedom of the Seas was superseded by the Oasis of the Seas in October 2009.
Because of changes in historic measurement systems, it is impossible to make meaningful and accurate comparisons of ship sizes over time beyond length. Three alternative forms of measurement are ship volume and weight of water it displaces. A fourth, deadweight tonnage, is a measure of how much mass a ship can safely carry, is thus more relevant to measuring cargo vessels than passenger ships. Gross register tonnage was a measure of the internal volume of certain enclosed areas of a ship divided into "tons" equivalent to 100 cubic feet of space; the displacement is a measure of both a ship's weight and the weight of water it displaces, which are one and the same by Archimedes' principle. While straightforward, it has four variants in measure, Loaded displacement, Light displacement, Normal displacement, Standard displacement. Of these, the first is most appropriate to measuring a passenger vessel. Gross tonnage is a comparatively new measure, only adopted in 1982 to replace GRT, it is calculated based on "the moulded volume of all enclosed spaces of the ship", is used to determine things such as a ship's manning regulations, safety rules, registration fees, port dues.
It is produced by a mathematical formula, does not distinguish between mechanical and passenger spaces, thus is not directly comparable to historic GRT measurements. While a high displacement can indicate better sea keeping abilities, gross tonnage is nowadays promoted as the most important measure of size for passenger vessels, as the ratio of gross tonnage per passenger – the Passenger/Space Ratio – gives a sense of the spaciousness of a ship, an important consideration in cruise liners where the onboard amenities are of high importance. A ship's GRT and displacement were somewhat similar
An oil tanker known as a petroleum tanker, is a ship designed for the bulk transport of oil or its products. There are two basic types of oil tankers: product tankers. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. For example, moving crude oil from oil wells in Nigeria to the refineries on the coast of the United States. Product tankers much smaller, are designed to move refined products from refineries to points near consuming markets. For example, moving gasoline from refineries in Europe to consumer markets in Nigeria and other West African nations. Oil tankers are classified by their size as well as their occupation; the size classes range from inland or coastal tankers of a few thousand metric tons of deadweight to the mammoth ultra large crude carriers of 550,000 DWT. Tankers move 2,000,000,000 metric tons of oil every year. Second only to pipelines in terms of efficiency, the average cost of oil transport by tanker amounts to only two or three United States cents per 1 US gallon.
Some specialized types of oil tankers have evolved. One of these is a tanker which can fuel a moving vessel. Combination ore-bulk-oil carriers and permanently moored floating storage units are two other variations on the standard oil tanker design. Oil tankers have been involved in a number of high-profile oil spills; as a result, they are subject to operational regulations. The technology of oil transportation has evolved alongside the oil industry. Although human use of oil reaches to prehistory, the first modern commercial exploitation dates back to James Young's manufacture of paraffin in 1850. In the early 1850s, oil began to be exported from Upper Burma a British colony; the oil was moved in earthenware vessels to the river bank where it was poured into boat holds for transportation to Britain. In the 1860s, Pennsylvania oil fields became a major supplier of oil, a center of innovation after Edwin Drake had struck oil near Titusville, Pennsylvania. Break-bulk boats and barges were used to transport Pennsylvania oil in 40-US-gallon wooden barrels.
But transport by barrel had several problems. The first problem was weight: they weighed 64 pounds, representing 20% of the total weight of a full barrel. Other problems with barrels were their expense, their tendency to leak, the fact that they were used only once; the expense was significant: for example, in the early years of the Russian oil industry, barrels accounted for half the cost of petroleum production. In 1863, two sail-driven tankers were built on England's River Tyne; these were followed in 1873 by the first oil-tank steamer, built by Palmers Shipbuilding and Iron Company for Belgian owners. The vessel's use was curtailed by U. S. and Belgian authorities citing safety concerns. By 1871, the Pennsylvania oil fields were making limited use of oil tank barges and cylindrical railroad tank-cars similar to those in use today; the modern oil tanker was developed in the period from 1877 to 1885. In 1876, Ludvig and Robert Nobel, brothers of Alfred Nobel, founded Branobel in Azerbaijan, it was, during the late 19th century, one of the largest oil companies in the world.
Ludvig was a pioneer in the development of early oil tankers. He first experimented with carrying oil in bulk on single-hulled barges. Turning his attention to self-propelled tankships, he faced a number of challenges. A primary concern was to keep the cargo and fumes well away from the engine room to avoid fires. Other challenges included allowing for the cargo to expand and contract due to temperature changes, providing a method to ventilate the tanks; the first successful oil tanker was Zoroaster, which carried its 242 long tons of kerosene cargo in two iron tanks joined by pipes. One tank was forward of the midships engine room and the other was aft; the ship featured a set of 21 vertical watertight compartments for extra buoyancy. The ship had a length overall of 184 feet, a beam of 27 feet, a draft of 9 feet. Unlike Nobel tankers, the Zoroaster design was built small enough to sail from Sweden to the Caspian by way of the Baltic Sea, Lake Ladoga, Lake Onega, the Rybinsk and Mariinsk Canals and the Volga River.
In 1883, oil tanker design took a large step forward. Working for the Nobel company, British engineer Colonel Henry F. Swan designed a set of three Nobel tankers. Instead of one or two large holds, Swan's design used several holds which spanned the width, or beam, of the ship; these holds were further subdivided into starboard sections by a longitudinal bulkhead. Earlier designs suffered from stability problems caused by the free surface effect, where oil sloshing from side to side could cause a ship to capsize, but this approach of dividing the ship's storage space into smaller tanks eliminated free-surface problems. This approach universal today, was first used by Swan in the Nobel tankers Blesk and Lux. Others point to another design of Colonel Swan, as being the first modern oil tanker, it adopted the best practices from previous oil tanker designs to create the prototype for all subsequent vessels of the type. It was the first dedicated steam-driven ocean-going tanker in the world and was the first ship in which oil could be pumped directly into the vessel hull instead of being loaded in barrels or drums.
It was the first tanker with a horizontal bulkhead. The ship w
BL 6-inch Mk VII naval gun
The BL 6-inch gun Mark VII was a British naval gun dating from 1899, mounted on a heavy traveling carriage in 1915 for British Army service to become one of the main heavy field guns in the First World War, served as one of the main coast defence guns throughout the British Empire until the 1950s. The gun superseded the QF six-inch gun of the 1890s, a period during which the Royal Navy had evaluated QF technology for all classes of guns up to six inches to increase rates of fire. BL Mk VII returned to loading charges in silk bags after it was determined that with new single-action breech mechanisms a six-inch BL gun could be loaded, a vent tube inserted and fired as as a QF six inch gun. Cordite charges in silk bags stored for a BL gun were considered to represent a considerable saving in weight and magazine space compared to the bulky brass QF cartridge cases; the gun was introduced on the Formidable-class battleships of 1898 and went on to equip many capital ships, cruisers and smaller ships such as the Insect-class gunboat which served throughout World War II.
The Mk VIII in naval service was identical to the Mk VII, except that the breech opened to the left instead of to the right, for use as the left gun in twin turrets. In World War II the gun was used to arm British troop ships and armed merchant cruisers, including HMS Rawalpindi, which fought the German 11-inch gun battlecruisers Scharnhorst and Gneisenau in November 1939, HMS Jervis Bay which sacrificed herself to save her convoy from the 11-inch pocket battleship Admiral Scheer in November 1940; the Mk VII gun was first used as a field gun in France in 1915. It was mounted on an improvised rectangular-frame field carriage designed by Admiral Percy Scott; the carriage was based on a design. It was a successful carriage, except. A better carriage which allowed elevation to 22°, the MK II, was introduced early in 1916; this was followed by Mk V and VI carriages. The gun was operated by the Royal Garrison Artillery in batteries of four, as were all the larger field guns in World War I. Following a successful deployment in the Battle of the Somme, the role of the gun was defined as counter-battery fire.
They "were most effective for neutralising defences and for wire cutting with fuze 106". They were effective for long-range fire against "targets in depth"; the Mk VII was superseded by the lighter and longer-range BL 6-inch Gun Mk XIX, introduced from October 1916, but the Mk VII remained in service to the end of World War I. The 6-inch Mk VII gun, together with the 9.2-inch Mk X gun, provided the main coast defence throughout the British Empire, from the early 1900s until the abolition of coast artillery in the 1950s. Many guns were specially built for army coast defence use, following the decommissioning of many obsolete cruisers and battleships after World War I, their 6-inch Mk VII guns were recycled for coast defence. During World War I, 103 of these guns were in service in coastal defences around the UK; some of these, together with others at ports around the wider British Empire, played an important defence role in World War II and remained in service until the 1950s. A number of new similar guns with stronger barrels which allowed more powerful cordite charges to be used were manufactured for coast defence during World War II, were designated 6-inch BL Mark XXIV.
In the German raid on Scarborough and Whitby on 16 December 1914, a notable action was fought by the Durham Royal Garrison Artillery of the Territorial Force at Heugh and Lighthouse batteries defending Hartlepool. They duelled with the German battlecruisers Seydlitz and Moltke and Blücher, firing 112 rounds and scoring seven hits; the battlecruisers fired a total of 1,150 rounds at the town and the batteries causing 112 civilians and seven military killed.

World War II
World War II known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from over 30 countries; the major participants threw their entire economic and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China, it included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease, the only use of nuclear weapons in war. Japan, which aimed to dominate Asia and the Pacific, was at war with China by 1937, though neither side had declared war on the other. World War II is said to have begun on 1 September 1939, with the invasion of Poland by Germany and subsequent declarations of war on Germany by France and the United Kingdom.
From late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, 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, Finland and the Baltic states. Following the onset of campaigns in North Africa and East Africa, the fall of France in mid 1940, the war continued between the European Axis powers and the British Empire. War in the Balkans, the aerial Battle of Britain, the Blitz, the long Battle of the Atlantic followed. On 22 June 1941, the European Axis powers launched an invasion of the Soviet Union, opening the largest land theatre of war in history; this Eastern Front trapped most crucially the German Wehrmacht, into a war of attrition. In December 1941, Japan launched a surprise attack on the United States as well as European colonies in the Pacific. Following an immediate U. S. declaration of war against Japan, supported by one from Great Britain, the European Axis powers declared war on the U.
S. in solidarity with their Japanese ally. Rapid Japanese conquests over much of the Western Pacific ensued, perceived by many in Asia as liberation from Western dominance and resulting in the support of several armies from defeated territories; the Axis advance in the Pacific halted in 1942. Key setbacks in 1943, which included a series of German defeats on the Eastern Front, the Allied invasions of Sicily and Italy, Allied victories in the Pacific, cost the Axis its initiative and forced it into strategic retreat on all fronts. In 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained its territorial losses and turned toward Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in Central China, South China and Burma, while the Allies crippled the Japanese Navy and captured key Western Pacific islands; the war in Europe concluded with an invasion of Germany by the Western Allies and the Soviet Union, culminating in the capture of Berlin by Soviet troops, the suicide of Adolf Hitler and the German unconditional surrender on 8 May 1945.
Following the Potsdam Declaration by the Allies on 26 July 1945 and the refusal of Japan to surrender under its terms, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki on 6 and 9 August respectively. With an invasion of the Japanese archipelago imminent, the possibility of additional atomic bombings, the Soviet entry into the war against Japan and its invasion of Manchuria, Japan announced its intention to surrender on 15 August 1945, cementing total victory in Asia for the Allies. Tribunals were set up by fiat by the Allies and war crimes trials were conducted in the wake of the war both against the Germans and the Japanese. World War II changed the political social structure of the globe; the United Nations was established to foster international co-operation and prevent future conflicts. The Soviet Union and United States emerged as rival superpowers, setting the stage for the nearly half-century long Cold War. In the wake of European devastation, the influence of its great powers waned, triggering the decolonisation of Africa and Asia.
Most countries whose industries had been damaged moved towards economic expansion.
