Uganda officially the Republic of Uganda, is a landlocked country in East Africa. Uganda is bordered on the east by Kenya, on the north by South Sudan, on the west by the Democratic Republic of the Congo, on the southwest by Rwanda, and on the south by Tanzania. The southern part of the country includes a substantial portion of Lake Victoria, shared with Kenya and Tanzania. Uganda takes its name from the Buganda kingdom, which encompasses a large portion of the south of the country including the capital Kampala. The people of Uganda were hunter-gatherers until 1,700 to 2,300 years ago, when Bantu-speaking populations migrated to the southern parts of the country.
