Prehistory

Archeological finds in Central Africa have been made which date back over 100,000 years. According to Zagato and Holl, there is evidence of iron smelting in the Central African Republic that may date back to 3000 to 2500 BCE. Extensive walled settlements have recently been found in Northeast Nigeria, approximately 60 km (37 mi) southwest of Lake Chad dating to the first millennium BCE.

Trade and improved agricultural techniques supported more sophisticated societies, leading to the early civilizations of West Africa: Sao, Kanem, Bornu, Shilluk, Baguirmi, and Wadai.

Around 2500 BCE, Bantu migrants had reached the Great Lakes Region in Central Africa. Halfway through the first millennium BCE, the Bantu had also settled as far south as what is now Angola.
