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.
Secretary of State for India
In 1937, the India Office was reorganised which separated Burma and Aden under a new Burma Office, but the same Secretary of State headed both Departments and a new title was established as His Majesty's Principal Secretary of State for India and Burma. The India Office and its Secretary of State were abolished in August 1947, when the United Kingdom granted independence in the Indian Independence Act, which created two new independent dominions, the Dominion of India and the Dominion of Pakistan. Burma soon achieved independence separately in early 1948.
