The Hausa are one of West Africa’s largest ethnic groups, with tens of millions of speakers across northern Nigeria and southern Niger. For centuries before the 19th century they organized themselves into independent city-states (Kano, Katsina, Zaria, and others) among the great commercial centers of the Sahel, before most were absorbed into the Sokoto Caliphate in 1808.
Hausa has been a written literary language since at least the 14th century, and today, spoken by tens of millions across Niger and Nigeria, functions as a trade lingua franca across West African marketplaces regardless of a speaker’s first language.
