Uganda, officially the Republic of Uganda is a sovereign country located in East Africa. Its form of government is that of a presidentialist republic, whose territory is composed of 111 districts. Its capital and most populated city is Kampala with 1,208,544 inhabitants. The country borders on the southeast with Lake Victoria, on the east with Kenya, on the north with South Sudan, on the west with the Democratic Republic of the Congo and on the southwest with Rwanda and Tanzania.
