Uganda

From 1945 or earlier until after independence, Uganda was divided into four provinces (around 1960 also named regions). During at least part of this period, the provinces were subdivided into districts http://www.statoids.com/uug.html).
Presently, Uganda is divided into (ca.) eighty districts, spread across four administrative regions: Northern, Eastern, Central and Western. The districts are subdivided into counties.
