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.
Viceroy
The viceroys reported directly to the Secretary of State for India in London and were advised by the Council of India. They were largely unencumbered in the exercise of their authority and were among the most powerful men on earth in the Victorian and Edwardian eras, ruling over an entire subcontinent with a large military force at their disposal in the form of the British Indian Army. Under the terms of the Government of India Act 1919, viceroys shared some limited aspects of their authority with the Central Legislative Assembly, one of the first steps in the establishment of Indian home rule. This process was accelerated by the Government of India Act 1935 and ultimately led to the independence of India and Pakistan as dominions in 1947. Both countries finally severed complete ties with Britain when they became republics – India as a secular republic in 1950 and Pakistan as an Islamic republic in 1956.
