The 1947 Indian Independence Act [1947 c. 30 (10 & 11. Geo. 6.)] is an Act of the Parliament of the United Kingdom that partitioned British India into the two new independent dominions of India and Pakistan. The Act received the Royal Assent on 18 July 1947 and thus India and Pakistan, comprising West (modern-day Pakistan) and East (modern-day Bangladesh) regions, came into being on 14 August.
