New Provinces
When West Pakistan was dissolved, the divisions were regrouped into four new provinces. Gradually over the late 1970s, new divisions were formed; Hazara and Kohat divisions were split from Peshawar Division; Gujranwala Division was formed from parts of Lahore and Rawalpindi divisions; Dera Ghazi Khan Division was split from Multan Division; Faisalabad Division was split from Sargodha Division; Sibi Division was formed from parts of Kalat and Quetta divisions; Lasbela District was transferred from Karachi Division to Kalat Division; Makran Division split from Kalat Division. The name of Khairpur Division was changed to Sukkur Division.
During the military rule of General Zia-ul-Haq, the Advisory Council of Islamic Ideology (headed by Justice Tanzilur Rahman) was tasked with finding ways to Islamicise the country. One of its recommendations was that the existing four provinces should be dissolved and the twenty administrative divisions should become new provinces in a federal structure with greater devolution of power, but this proposal was never implemented.
In the early 1990s, Naseerabad division was split from Sibi Division; Zhob Division was split from Quetta Division; Bannu Division was split from Dera Ismail Khan Division; Mardan Division was split from Peshawar Division; Larkana Division was split from Sukkur Division; Mirpur Khas Division was split from Hyderabad Division. The capital of Kalat Division was moved from Kalat to Khuzdar. 64Gul
