The modern state of Pakistan was established on 14 August 1947 in the eastern and northwestern regions of British India, where there was a Muslim majority. It comprised the provinces of Balochistan, East Bengal, the North-West Frontier Province, West Punjab and Sindh. From 1947 to 1956, Pakistan was a dominion in the Commonwealth of Nations under two monarchs. In 1947, King George VI relinquished the title of Emperor of India and became King of Pakistan. He retained that title until his death on 6 February 1952, after which Queen Elizabeth II became Queen of Pakistan. She retained that title until Pakistan became an Islamic and Parliamentary republic in 1956.
