The regions of Uganda are known as Central region, Western religion, Eastern religion, and Northern region. These four regions are in turn divided into districts. 

There were 56 districts in 2002, which expanded into 111 districts plus one city (Kampala) by 2010.

The national government interacts directly with the districts today, so regions do not have any definite role in the administration.

Under British rule prior to 1962 the regions were functional administrative units and were called provinces, headed by a Provincial Commissioner.

The central region is the kingdom of Buganda, which then had a semi-autonomous government headed by the Kabaka (king). 

The equivalent of the Privincial commissioner for Buganda was called the Resident. (ref, Uganda Protectorate annual report, Government Printer, Entebbe, 1959).

At Uganda’s 2002 census, the Central region contained 27% of the country’s population, the Western region contained 26%, and Eastern region 25%, and the Northern region had 22%.

The administrational role which enabled the regions to mantain their identity of archarchism, and the autonomous governace of the kingdom of Buganda which Buganda had over the central region was discontinued through the imposed rules of colonialism that made Uganda into a state.
