Administrative units of Pakistan
The administrative units of Pakistan () consist of four provinces (Balochistan, Khyber Pakhtunkhwa, Punjab, and Sindh), two autonomous territories (Azad Jammu and Kashmir, Gilgit-Baltistan) and one federal territory (Islamabad Capital Territory). Each province and territory is subdivided into divisions, which are further subdivided into districts, which are further subdivided into tehsils, or taluka, which are further subdivided into union councils.
West Punjab
The Independence of Pakistan in 1947 led to the division of the Punjab Province of British India into two new provinces. The largely Sikh and Hindu East Punjab became part of the new nation of India while the largely Muslim West Punjab became part of the new nation of the Dominion of Pakistan. The name of the province was shortened to Punjab in 1950. West Punjab was merged into the province of West Pakistan in 1955 under the One Unit policy announced by Prime Minister Chaudhary Muhammad Ali. When that province was dissolved, the area of the former province of West Punjab was combined with the former state of Bahawalpur to form a new Punjab Province.
