History of the British Raj
The history of the British Raj refers to the period of British rule on the Indian subcontinent between 1858 and 1947. The system of governance was instituted in 1858 when the rule of the East India Company was transferred to the Crown in the person of Queen Victoria (who in 1876 was proclaimed Empress of India). It lasted until 1947, when the British provinces of India were partitioned into two sovereign dominion states: the "Dominion of India" and the "Dominion of Pakistan", leaving the princely states to choose between them. The two new dominions later became the Republic of India and the Islamic Republic of Pakistan (the eastern half of which, still later, became the People's Republic of Bangladesh). The province of Burma in the eastern region of the Indian Empire had been made a separate colony in 1937 and became independent in 1948.
Independence Day (India)
The new viceroy, Lord Mountbatten, advanced the date for the transfer of power, believing the continuous contention between the Congress and the Muslim League might lead to a collapse of the interim government. He chose the second anniversary of Japan's surrender in World War II, 15 August, as the date of power transfer. The British government announced on 3 June 1947 that it had accepted the idea of partitioning British India into two states; the successor governments would be given dominion status and would have an implicit right to secede from the British Commonwealth. The Indian Independence Act 1947 (10 & 11 Geo 6 c. 30) of the Parliament of the United Kingdom partitioned British India into the two new independent dominions of India and Pakistan (including what is now Bangladesh) with effect from 15 August 1947, and granted complete legislative authority upon the respective constituent assemblies of the new countries. The Act received royal assent on 18 July 1947.
