Sokoto
Sokoto, in northwestern Nigeria, was the capital of the Sokoto Caliphate founded in the early 19th century after the jihad of Usman dan Fodio (d. 1817), a Fulani scholar and reformer whose movement created one of the largest states in 19th-century Africa. The West African reformer al-Hajj Umar Tal was linked to this Fulani jihad tradition.
