Collier's New Encyclopedia (1921)
2026 Editor's Note: This page uses language about race that was commonplace when the book was published and is offensive by today's standards. The text has been left exactly as it was printed, rather than cut or softened, so that the historical record — including how ordinary such language once was — is preserved. (Ed: ET 2026-07-22) the ethnological name of a group of African races dwelling about 6° N. lat., and including the Kaffirs, Zulus, Bechuanas, the tribes of the Loango, Kongo, etc., but not the Hottentots. The term Bantu is also used to denote the homogeneous family of languages spoken in Africa throughout the vast region lying between Kamerun, Zanzibar, and the Cape of Good Hope, with the exception of the Hottentot, Bushmen, and Pigmy enclaves.
Aiton's Encyclopedia (1910)
in African geography, a general term for a vast number of negro tribes and languages. The other great group of negroes is the Nigritic or Sudan. The Hottentots, Bushmen, and pygmies are excluded from both groups. In general, the Bantu tribes inhabit that part of Africa lying south of the Sudan and Abyssinia. The Congo, Kaffir, and Zulu negroes are of this stock. 2026 Editor's Note: This page uses language about race that was commonplace when the book was published and is offensive by today's standards.

(Ed: BR 2026-07-22) 2026 Editor's Note: The term is now handled with care: apartheid South Africa turned 'Bantu' into a demeaning racial label and herded Black citizens into puppet 'Bantustans,' so it is largely avoided today except for the language family. That family — including Swahili and Zulu — is spoken by hundreds of millions, spread by the ' Bantu expansion ,' one of the great farming migrations of human history. The entry's talk of 'negro tribes' reflects the crude racial categories of its era, not how these peoples are understood today. (Ed: BR 2026-06-25)
