West Punjab
The independence of Pakistan in 1947 led to the divisions of the Punjab province into two new provinces. The East Punjab where most people were Sikh and Hindu became part of the new nation of India while the mainly Muslim West Punjab became part of the new nation 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 Chaudhry Mohammad 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.
