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 were thirteen
princely states and parts of
Kashmir. In 1948, the area around
Karachi was separated from Sind province to form the
Federal Capital Territory. In 1950 the
North-West Frontier Province was expanded to include the small states of
Amb and
Phulra and the name of West Punjab province was changed to Punjab. The
Baluchistan States Union was formed in 1952 by the four princely states of southwest Pakistan. Thus, between 1947 and 1955, Pakistan comprised five provinces and one territory. The western wing eventually included thirteen
princely states, one union of states, Gwadar enclave, Gilgit agency and parts of Kashmir: •
Gilgit Agency (former agency of Kashmir – after independence on 1 November 1947, using flag of
Muslim League) •
Azad Jammu and Kashmir (after Kashmir War 1947~48 - using newly AJK Flag ) •
Baluchistan States Union (combining Kalat, Kharan, Las Bela and Makran in 1953 – using flag of Kalat) •
Gwadar Enclave (purchased from Sultanate of Oman in 1958) ==One Unit of Pakistan 1955==
