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 Pakistan
Pakistan was formed from two distinct areas, separated by a thousand miles and India. The western state was composed of three Governor's provinces (North-West Frontier, West-Punjab and Sindh Province), one Chief Commissioner's province (Baluchistan Province), the Baluchistan States Union, several other princely states (notably Bahawalpur, Chitral, Dir, Hunza, Khairpur and Swat), the Federal Capital Territory (around Karachi) and the tribal areas. The eastern wing of the new country – East Pakistan – formed the single province of East Bengal, including the former Assam district of Sylhet.
