In July 1960, there were six provinces in the Belgian Congo: Leopoldville Province, Equateur Province, Province Orientale, Kivu Province, Katanga Province, and Kasai Province. Kivu Province existed from 1933 to 1962 (under the name Province de Costermansville until 1947, from the name of its capital) and from 1966 to 1988.
Over 200 ethnic groups populate the Democratic Republic of the Congo, of which the majority are Bantu peoples. Together, Mongo, Luba and Kongo peoples (Bantu) and Mangbetu-Azande peoples constitute around 45% of the population.
The Democratic Republic of the Congo (DRC) is located in central sub-Saharan Africa, bounded by (clockwise from the southwest) Angola, the South Atlantic Ocean, the Republic of Congo, the Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania across Lake Tanganyika, and Zambia. The country lies between latitudes 6°N and 14°S, and longitudes 12° and 32°E. It straddles the Equator, with one-third to the North and two-thirds to the South.
