The One Unit (Urdu: ون یونٹ) was a geopolitical program launched by the government of Pakistan led by then-Prime Minister Muhammad Ali Bogra on 22November 1954. The program was believed to be enacted after the government faced difficulty of administrating the two unequal polities of Pakistan separated from each other by more than a thousand miles. To diminish the differences between the two regions, the program merged the Four Provinces of West Pakistan into a single province as was the case with East Pakistan (now Bangladesh).
