The partition of India in 1947 was the division of British India into two independent dominion states, the Union of India and Dominion of Pakistan. The Union of India is today the Republic of India, and the Dominion of Pakistan is the Islamic Republic of Pakistan and the People's Republic of Bangladesh. The partition involved the division of two provinces, Bengal and the Punjab, based on district-wide non-Muslim (mostly Hindu and Sikh) or Muslim majorities.
