The Democratic Republic of the Congo, also known as DR Congo, the DRC, DROC, Congo-Kinshasa, or simply the Congo, is a country located in Central Africa. It was formerly called Zaire. It is, by area, the largest country in sub-Saharan Africa, the second-largest in all of Africa, and the 11th-largest in the world. With a population of over 84 million, the Democratic Republic of the Congo is the most populous officially Francophone country, the fourth-most-populous country in Africa, and the 16th-most-populous country in the world. Eastern DR Congo has been the scene of ongoing military conflict in Kivu, since 2015.
Centred 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 centre and east, the kingdoms of Luba and Lunda ruled from the 16th and 17th centuries to the 19th century.
