West Pakistan
The province of West Pakistan was created on 14 October 1955 by the merger of the provinces, states and tribal areas of the western wing. The province was composed of twelve divisions and the provincial capital was established at Lahore. The province of East Bengal was renamed East Pakistan with the provincial capital at Dacca. The federal government moved in 1959 from Karachi to Rawalpindi (provisional capital until Islamabad was finished), whilst the federal legislature moved to DACCA.
