The Sosso kingdom (12th to 13th centuries) briefly flourished in the void but the Islamic Mandinka Mali Empire came to prominence when Soundiata Kéïta defeated the Sosso ruler, Sumanguru Kanté at the semi-historical Battle of Kirina in c. 1235. The Mali Empire was ruled by Mansa (Emperors), the most famous 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.
