paragraph_text: Kolkata, formerly known as Calcutta in English, is the capital of the Indian state of West Bengal and is located in eastern India on the east bank of the River Hooghly. The city was a colonial city developed by the British East India Company and then by the British Empire. Kolkata was the capital of the British Indian empire until 1911 when the capital was relocated to Delhi. Kolkata grew rapidly in the 19th century to become the second city of the British Indian Empire. This was accompanied by the development of a culture that fused European philosophies with Indian tradition.

paragraph_text: The Sri Lankan independence movement was a peaceful political movement which aimed at achieving independence and self - rule for Sri Lanka, then Ceylon, from the British Empire. It was initiated around the turn of the 20th century and led mostly by the educated middle class. It succeeded when, on February 4, 1948, Ceylon was granted independence as the Dominion of Ceylon. Dominion status within the British Commonwealth was retained for the next 24 years until May 22, 1972 when it became a republic and was renamed the Republic of Sri Lanka.

paragraph_text: Calcutta (now Kolkata) was the capital of India during the British Raj until December 1911. However, Delhi had served as the political and financial centre of several empires of ancient India and the Delhi Sultanate, most notably of the Mughal Empire from 1649 to 1857. During the early 1900s, a proposal was made to the British administration to shift the capital of the British Indian Empire (as it was officially called) from Calcutta to Delhi. Unlike Calcutta, which was located on the eastern coast of India, Delhi was at the centre of northern India and the Government of British India felt that it would be logistically easier to administer India from the latter rather than the former.

paragraph_text: The British Empire, consolidated during the period of British maritime hegemony in the 19th century, became the largest empire in history by virtue of the improved transportation technologies of the time. At its height, the British Empire covered a quarter of the Earth's land area and comprised a quarter of its population. During the New Imperialism, Italy and Germany also built their colonial empires in Africa.

paragraph_text: French involvement in the American Revolutionary War began in 1775, when France, a rival of the British Empire, secretly shipped supplies to the Continental Army. A Treaty of Alliance in 1778 soon followed, which led to shipments of money and matériel to the United States. Subsequently, the Spanish Empire and the Dutch Republic also began to send assistance, leaving the British Empire with no allies.

paragraph_text: The name was changed from Saxe - Coburg and Gotha to the English Windsor in 1917 because of anti-German sentiment in the British Empire during World War I. During the reign of the Windsors, major changes took place in British society. The British Empire participated in the First and Second World Wars, ending up on the winning side both times, but subsequently lost its status as a superpower during decolonisation. Much of Ireland broke with the United Kingdom and the remnants of the Empire became the Commonwealth of Nations.

paragraph_text: During George's reign the break-up of the British Empire and its transition into the Commonwealth of Nations accelerated. The parliament of the Irish Free State removed direct mention of the monarch from the country's constitution on the day of his accession. From 1939, the Empire and Commonwealth, except Ireland, was at war with Nazi Germany. War with Italy and Japan followed in 1940 and 1941, respectively. Though Britain and its allies were ultimately victorious in 1945, the United States and the Soviet Union rose as pre-eminent world powers and the British Empire declined. After the independence of India and Pakistan in 1947, George remained as king of both countries, but the title Emperor of India was abandoned in June 1948. Ireland formally declared itself a republic and left the Commonwealth in 1949, and India became a republic within the Commonwealth the following year. George adopted the new title of Head of the Commonwealth. He was beset by health problems in the later years of his reign. His elder daughter, Elizabeth, succeeded him.

paragraph_text: If the British Empire was now going to side with the Russian Empire, the Ottoman Empire had no choice but to cultivate a relationship with the Austro-Hungarian Empire, which was supported by the German Empire. In a few years these alignments became the Triple Entente and the Triple Alliance (already formed in 1882), which were in part a cause of World War I. By its end in 1918 three empires were gone, a fourth was about to fall to revolution, and two more, the British and French, were forced to yield in revolutions started under the aegis of their own ideologies.

paragraph_text: From 1940, the Sovereign could appoint a person as a Commander, Officer or Member of the Order of the British Empire for gallantry for acts of bravery (not in the face of the enemy) below the level required for the George Medal. The grade was determined by the same criteria as usual, and not by the level of gallantry (and with more junior people instead receiving the British Empire Medal). Oddly, this meant that it was awarded for lesser acts of gallantry than the George Medal, but, as an Order, was worn before it and listed before it in post-nominal initials. From 14 January 1958, these awards were designated the Order of the British Empire for Gallantry.

paragraph_text: Ornamentalism: How the British Saw Their Empire is a book by David Cannadine about British perceptions of the British Empire. Cannadine argues that class, rank and status were more important to the British Empire than race. The title of the work "Ornamentalism" is a direct reference to Edward Said's book "Orientalism", which argues the existence of prejudiced outsider interpretations of the East, shaped by the attitudes of European imperialism in the 18th and 19th centuries. It has also been argued to borrow tones from the title of Joseph Schumpeter's "Imperialism and Social Classes", which some historians see as the origins of the 'Ornamentalist' perspective in academic history'

paragraph_text: Any individual made a member of the Order for gallantry could wear an emblem of two crossed silver oak leaves on the same riband, ribbon or bow as the badge. It could not be awarded posthumously and was effectively replaced in 1974 with the Queen's Gallantry Medal. If recipients of the Order of the British Empire for Gallantry received promotion within the Order, whether for gallantry or otherwise, they continued to wear also the insignia of the lower grade with the oak leaves. However, they only used the post-nominal letters of the higher grade.

paragraph_text: The name was changed from Saxe - Coburg and Gotha to the English Windsor (from ``Windsor Castle '') in 1917 because of anti-German sentiment in the British Empire during World War I. There have been four British monarchs of the house of Windsor to date: three kings and the present queen, Elizabeth II. During the reign of the Windsors, major changes took place in British society. The British Empire participated in the First and Second World Wars, ending up on the winning side both times, but subsequently lost its status as a superpower during decolonisation. Much of Ireland broke with the United Kingdom and the remnants of the Empire became the Commonwealth of Nations.

paragraph_text: Imperialism has played an important role in the histories of Japan, Korea, the Assyrian Empire, the Chinese Empire, the Roman Empire, Greece, the Byzantine Empire, the Persian Empire, the Ottoman Empire, Ancient Egypt, the British Empire, India, and many other empires. Imperialism was a basic component to the conquests of Genghis Khan during the Mongol Empire, and of other war-lords. Historically recognized Muslim empires number in the dozens. Sub-Saharan Africa has also featured dozens of empires that predate the European colonial era, for example the Ethiopian Empire, Oyo Empire, Asante Union, Luba Empire, Lunda Empire, and Mutapa Empire. The Americas during the pre-Columbian era also had large empires such as the Aztec Empire and the Incan Empire.

paragraph_text: Kolonnawa electoral district was an electoral district of Sri Lanka between March 1960 and February 1989. The district was named after the town of Kolonnawa in Colombo District, Western Province. The 1978 Constitution of Sri Lanka introduced the proportional representation electoral system for electing members of Parliament. The existing 160 mainly single-member electoral districts were replaced with 22 multi-member electoral districts. Kolonnawa electoral district was replaced by the Colombo multi-member electoral district at the 1989 general elections.

paragraph_text: Following the defeat of the Boers in the Anglo - Boer or South African War (1899 -- 1902), the Union of South Africa was created as a dominion of the British Empire in terms of the South Africa Act 1909, which amalgamated the four previously separate British colonies: Cape Colony, Natal Colony, Transvaal Colony and Orange River Colony. The country became a self - governing nation state within the British Empire, in 1934 following enactment of the Status of the Union Act. The dominion came to an end on 31 May 1961 as the consequence of a 1960 referendum, which legitimised the country becoming a sovereign state named Republic of South Africa. A republican constitution was adopted.

paragraph_text: Prior to the creation of the UK, Wales had been conquered and annexed by the Kingdom of England. This meant that the United Kingdom created in 1707 by the Treaty of Union between England and Scotland encompassed all of Great Britain. The Kingdom of Ireland merged with this state in 1801 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 and Northern Ireland. There are fourteen British Overseas Territories, the remnants of the British Empire which, at its height in the 1920s, encompassed almost a quarter of the world's land mass and was the largest empire in history. British influence can be observed in the language, culture and legal systems of many of its former colonies.

paragraph_text: At the foundation of the Order, the "Medal of the Order of the British Empire" was instituted, to serve as a lower award granting recipients affiliation but not membership. In 1922, this was renamed the "British Empire Medal". It stopped being awarded by the United Kingdom as part of the 1993 reforms to the honours system, but was again awarded beginning in 2012, starting with 293 BEMs awarded for the Queen's Diamond Jubilee. In addition, the BEM is awarded by the Cook Islands and by some other Commonwealth nations. In 2004, a report entitled "A Matter of Honour: Reforming Our Honours System" by a Commons committee recommended to phase out the Order of the British Empire, as its title was "now considered to be unacceptable, being thought to embody values that are no longer shared by many of the country’s population".
