ハウサ諸王国
Usman Dan Fodiyo assembled an Islamic army to lead a jihad against the Hausa Kingdoms of north Nigeria. The forces of Usman Danfodiyo slowly took over more and more of the Hausa kingdoms, capturing Gobir in 1808 and executing Yunfa. The war resulted in the creation of the Sokoto Caliphate, headed by Usman Danfodiyo, which became one of the largest states in Africa in the 19th century. His success inspired similar jihads in Western Africa.
