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)
The Indian Independence Act 1947 (10 & 11 Geo 6 c. 30) passed by the Parliament of the United Kingdom divided British India into the two new independent dominions; the Dominion of India (later to become the Republic of India) and the Dominion of Pakistan (later to become the Islamic Republic of Pakistan). The act provided a mechanism for division of the Bengal and Punjab provinces between the two nations (see partition of India), establishment of the office of the Governor-General, conferral of complete legislative authority upon the respective Constituent Assemblies, and division of joint property between the two new countries. The act later received royal assent on 18 July 1947. The partition was accompanied by violent riots and mass casualties, and the displacement of nearly 15 million people due to religious violence across the subcontinent; millions of Muslim, Sikh and Hindu refugees trekked the newly drawn borders to Pakistan and India respectively in the months surrounding independence. On 14 August 1947, the new Dominion of Pakistan became independent and Muhammad Ali Jinnah was sworn in as its first governor general in Karachi. Independence was marked with widespread celebration, but the atmosphere remained heated given the communal riots prevalent during independence in 1947.
