The origins of most of the former administrative units lay in the set-up inherited from British India. From 1947 to 1971 newly independent Pakistan comprised two wings - 1600 kilometres apart and separated by India. The eastern wing comprised the single province of East Bengal, which included the Sylhet District from the former British Indian province of Assam as well as the Buddhist-majority Chittagong Hill Tracts awarded by the Radcliffe Commission. The politically dominant western wing united three Governor's provinces (North-West Frontier Province (NWFP), West Punjab and Sind), and one Chief Commissioner's Province (Baluchistan), also included thirteen princely states and parts of Kashmir.
