The Bamana Empire was one of the largest states of West Africa in the 18th century. Along with Kaarta it was one of the most important successors of the Songhai Empire. Based on an earlier kingdom established in 1640, it grew into a powerful empire in the early 18th century under Bitòn Coulibaly. The empire existed as a centralized state from 1712 until the 1861 invasion by the Toucouleur conqueror El Hadj Umar Tall.
