Mali Empire
The Sosso Empire (12th to 13th centuries) briefly flourished in the resulting void, but the Mali Empire came to prominence when Soundiata Kéïta defeated the Sosso ruler Soumangourou Kanté at the Battle of Kirina, in c. 1235. The Mali Empire was ruled by Mansa (Emperors), the most notable being Kankou Moussa, who made a famous hajj to Mecca in 1324. Shortly after his reign, the Mali Empire began to decline and was ultimately supplanted by its vassal states in the 15th century.
