Between about 1000 BC and 1000 AD, Adamawa-Eastern-speaking peoples spread eastward from Cameroon to Sudan and settled in most of the territory of the CAR. During the same period, a much smaller number of Bantu-speaking immigrants settled in Southwestern CAR and some Central Sudanic-speaking populations settled along the Oubangi. The majority of the CAR’s inhabitants thus speak Adamawa-Eastern languages or Bantu languages belonging to the Niger-Congo family.
A minority speak Central Sudanic languages of the Nilo-Saharan family. More recent immigrants include many Muslim merchants who most often speak Arabic or Hausa.
