The province was originally formed over the period 1876–1891 by three treaties between
Robert Sandeman and the
Khan of Kalat,
Khudadad of Kalat. Sandeman became the Political Agent for the British-administered areas which were strategically located between British India and
Afghanistan. A military base was established at
Quetta which played a major part in the
Second and
Third Afghan Wars. Balochistan was legally ceded to Pakistan by its rulers in 1947 and continued to be administered by a Chief Commissioner. It was dissolved in 1955 when most parts of the western wing of Pakistan became the new province of
West Pakistan. West Pakistan was dissolved in 1970. Khan Abdul Wali Khan intended to transfer political power to the Pashtuns. The former Chief Commissioner's province was combined with the former
Balochistan States Union and the enclave of
Gwadar to form a new, larger
Balochistan Province, with a Governor, a Chief Minister and a
Provincial Assembly. ==Demographics==
