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.
Kashmir conflict
British rule in the Indian subcontinent ended in 1947 with the creation of new states: the Dominion of Pakistan and the Union of India, as the successor states to British India. The British Paramountcy over the 562 Indian princely states ended. According to the Indian Independence Act 1947, "the suzerainty of His Majesty over the Indian States lapses, and with it, all treaties and agreements in force at the date of the passing of this Act between His Majesty and the rulers of Indian States". States were thereafter left to choose whether to join India or Pakistan or to remain independent. Jammu and Kashmir, the largest of the princely states, had a predominantly Muslim population ruled by the Hindu Maharaja Hari Singh. He decided to stay independent because he expected that the State's Muslims would be unhappy with accession to India, and the Hindus and Sikhs would become vulnerable if he joined Pakistan. On 11 August, the Maharaja dismissed his prime minister Ram Chandra Kak, who had advocated independence. Observers and scholars interpret this action as a tilt towards accession to India. Pakistanis decided to preempt this possibility by wresting Kashmir by force if necessary.
