Sokoto Caliphate
Usuman dan Fodio ,The 18th century revolutionary and a social, religious and political reformer finally united the 7 Hausa States with newly created provinces into the Sokoto Caliphate. The Sokoto Caliphate was under the overall authority of the Commander of the Faithful. Under Dan Fodio, the Empire was bicephalous and divided into two territories each controlled by an appointed vizier. Each of the territories was further divided into autonomous Emirates under mainly hereditary local Emirs. The Bornu Empire was initially absorbed into the Sokoto Caliphate of Usman dan Fodio, but broke away a few years later.
