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 (India)
European traders had established outposts in the Indian subcontinent by the 17th century. Through overwhelming military strength, the British East India company subdued local kingdoms and established themselves as the dominant force by the 18th century. Following the First War of Independence of 1857, the Government of India Act 1858 led the British Crown to assume direct control of India. In the decades following, civic society gradually emerged across India, most notably the Indian National Congress Party, formed in 1885. The period after World War I was marked by British reforms such as the Montagu–Chelmsford Reforms, but it also witnessed the enactment of the repressive Rowlatt Act and calls for self-rule by Indian activists. The discontent of this period crystallised into nationwide non-violent movements of non-cooperation and civil disobedience, led by Mohandas Karamchand Gandhi.
