From history.com, THIS DAY IN HISTORY August 15, 1947, India and Pakistan win autonomy:
"The Indian Independence Bill, which cuts the autonomous countries of India and Pakistan out of the previous Mogul Empire, comes into force at the stroke of 12 PM on August 15, 1947. The hotly anticipated understanding finished 200 years of British rule and was hailed by Indian freedom pioneer Mohandas Gandhi as the 'noblest demonstration of the British country.'"
From the Central Intelligence Agency, The World Factbook, Pakistan, Introduction, Background:
"The partition in 1947 of British India into the Muslim province of Pakistan (with West and East segments) and to a great extent Hindu India was rarely sufficiently settled, and India and Pakistan battled two conflicts and a restricted struggle - in 1947-48, 1965, and 1999 separately - over the contested Kashmir region. A third conflict between these nations in 1971 - in which India helped a native development responding to the underestimation of Bengalis in Pakistani governmental issues - brought about East Pakistan turning into the different country of Bangladesh."
