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.
History of South India
On August 15, 1947, the former British India achieved independence as the new dominions of India and Pakistan. The rulers of India's princely states acceded to the government of India between 1947 and 1950, and South India was organized into a number of new states. Most of South India was included in Madras state, which included the territory of the former Madras Presidency together with the princely states of Banganapalle, Pudukkottai, and Sandur. The other states in South India were Coorg (the erstwhile Coorg province of British India), Mysore State (the former princely state of Mysore) and Travancore-Cochin, formed from the merger of the princely states of Travancore and Cochin. The former princely state of Hyderabad became Hyderabad State, and erstwhile Bombay Presidency became Bombay State.
