خلافة صكتو
The Sokoto Caliphate was an Islamic state in what is now Nigeria led by Usman dan Fodio. Founded during the Fulani War in the early 19th century, it controlled one of the most powerful empires in sub-Saharan Africa prior to European conquest and colonisation. The caliphate remained extant through the colonial period and afterwards, though with reduced power. The current head of the Sokoto Caliphate is Sa'adu Abubakar.
