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.
Administrative units of Pakistan
In 1955, the "One Unit Policy" was launched by Muhammad Ali Bogra, whereby all the provinces and princely states of the western wing were merged and formed West Pakistan, with Lahore as the provincial capital. Simultaneously, East Bengal (including Sylhet and the Hill Tracts) was renamed to East Pakistan, with Dacca as the provincial capital. The One Unit Policy aimed to reduce expenditure and to eliminate provincial prejudices, but the military coup of 1958 signaled difficulties when the first military President, Ayub Khan, abolished the office of Chief Minister of West Pakistan in favour of Governor's rule.
