The Democratic Republic of the Congo (DRC), also known as Congo-Kinshasa and formerly known as Zaire, is a country in Central Africa. By land area, the DRC is the second-largest country in Africa, after Algeria, and the 11th-largest in the world. With a population of around 112 million, the Democratic Republic of the Congo is the most populous officially Francophone country in the world. The national capital and largest city is Kinshasa, which is also the economic center. The country is bordered by the Republic of the Congo, Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania (across Lake Tanganyika), Zambia, Angola, the Cabinda exclave of Angola and the South Atlantic Ocean.
Centered on the Congo Basin, the territory of the DRC was first inhabited by Central African foragers around 90,000 years ago and was reached by the Bantu expansion about 3,000 years ago. In the west, the Kingdom of Kongo ruled around the mouth of the Congo River from the 14th to 19th centuries. In the northeast, center and east, the kingdoms of Azande, Luba, and Lunda ruled from the 16th and 17th centuries to the 19th century. King Leopold II of Belgium formally acquired rights to the Congo territory in 1885 and declared the land his private property, naming it the Congo Free State. From 1885 to 1908, his colonial military forced the local population to produce rubber and committed widespread atrocities. In 1908, Leopold ceded the territory, which thus became a Belgian colony.
