An Expansion, Not an Identity

The Bantu expansion is one of the largest movements of people in the human record. Beginning somewhere near the modern border of Nigeria and Cameroon, probably around three thousand years ago, speakers of one branch of Niger-Congo spread east and south until their descendants occupied most of the continent below a line drawn roughly from Cameroon to Kenya. They carried iron working, farming and a set of political institutions with them, and the archaeology, the linguistics and more recently the genetics broadly agree on the shape of it, while continuing to argue about the pace and the routes.

What resulted is several hundred related languages, from Swahili on the Indian Ocean coast to Zulu and Tswana in the far south, close enough that the relationship is obvious to a specialist and often audible to a speaker. What did not result is a people. There is no Bantu nation, no Bantu polity and, for most of the peoples covered, no sense of being Bantu. The word was coined by philologists in the nineteenth century from the term for people that recurs across the languages, and it names a fact about descent of speech. Reading it as a shared culture, or worse as a race, is the mistake this entry exists to head off.
