By the first millennium AD, Bantu-speaking farmers had moved into the region, initially along the coast. The Bantus originated in West Africa along the Benue River in what is now eastern Nigeria and western Cameroon. The Bantu migration brought new developments in agriculture and ironworking to the region. Bantu groups in Kenya include the Kikuyu, Luhya, Kamba, Kisii, Meru, Kuria, Aembu, Ambeere, Wadawida-Watuweta, Wapokomo, and Mijikenda, among others.
