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.
Independence Day (Pakistan)
In 1946, the Labour government in Britain, exhausted by recent events such as World War II and numerous riots, realized that it had neither the mandate at home, the support internationally, nor the reliability of the British Indian Army for continuing to control an increasingly restless British India. The reliability of the native forces for continuing their control over an increasingly rebellious India diminished, and so the government decided to end the British rule of the Indian Subcontinent. In 1946, the Indian National Congress, being a secular party, demanded a single state. The Muslim majorities, who disagreed with the idea of single state, stressed the idea of a separate Pakistan as an alternative. The 1946 Cabinet Mission to India was sent to try to reach a compromise between Congress and the Muslim League, proposing a decentralized state with much power given to local governments, but it was rejected by both of the parties and resulted in a number of riots in South Asia.
