The Dominion of Pakistan, officially Pakistan, was an independent federal dominion in the British Commonwealth of Nations, existing between 14 August 1947 and 23 March 1956, created by the passing of the Indian Independence Act 1947 by the British parliament, which also created an independent Dominion of India.

Independence Day, observed annually on 14 August, is a national holiday in Pakistan. It commemorates the day when Pakistan achieved independence and was declared a sovereign state following the termination of the British Raj in August 1947. Pakistan came into existence as a result of the Pakistan Movement, which aimed for the creation of an independent Muslim state in the north-western regions of British India via partition. The movement was led by the All-India Muslim League under the leadership of Muhammad Ali Jinnah. The event was brought forth by the Indian Independence Act 1947 under which the British Raj gave independence to the Dominion of Pakistan which comprised West Pakistan and East Pakistan. That year the day of independence coincided with 27 Ramadan of the Islamic calendar, the eve of which, one of the five nights on which Laylat al-Qadr may occur, is regarded as sacred by Muslims.
