Self-determination
In 1947, India gained independence from the British Empire. The empire was in decline but adapted to these circumstances by creating the British Commonwealth—since 1949 the Commonwealth of Nations—which is a free association of equal states. As India obtained its independence, multiple ethnic conflicts emerged in relation to the formation of a statehood during the Partition of India which resulted in Islamic Pakistan and Secular India. Before the advent of the British, no empire based in mainland India had controlled any part of what now makes up the country's Northeast, part of the reason for the ongoing insurgency in Northeast India. In 1971 Bangladesh obtained independence from Pakistan.
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.
