List of capitals in Pakistan
Islamabad officially became the capital of Pakistan on 14 August 1967, exactly 20 years after the country's independence. Previously, Rawalpindi was the capital, designated in 1958. The first capital of Pakistan was the coastal city of Karachi, which was selected by Muhammad Ali Jinnah. Karachi was and still is the largest city and economic capital of Pakistan. It remained the seat of government until 1959, when the military president, Ayub Khan, decided to build a new capital in the north of Pakistan, near the general headquarters of the Pakistani Armed Forces at Rawalpindi.
