The first Bantu people to arrive in Zambia came through the eastern route via the African Great Lakes. They arrived around the first millennium C.E, and among them were the Tonga people (also called Ba-Tonga, "Ba-" meaning "men") and the Ba-Ila and Namwanga and other related groups, who settled around Southern Zambia near Zimbabwe. Ba-Tonga oral records indicate that they came from the east near the "big sea".
