As Bitòn Coulibaly tightened his control over Ségou, capital of his newly founded Bambara Empire, a faction of Ségou Bambara dissatisfied with his rule fled west. In 1753, they founded the kingdom of Kaarta on the homeland of the long-defunct Ghana Empire, taking Nioro du Sahel as their capital. The kingdom was destroyed as an independent force in 1854 by El Hadj Umar Tall's jihad across West Africa; Umar Tall seized Nioro, and put the Kaarta king (Fama) Mamady Kandian and his entire family to death.
In 1878 the French governor of Senegal Briere de l'Isle sent a French force against the Kaarta Toucouleur vassal state along the north bank of the Senegal River. Blocked by the colonial minister in Paris, he argued that they were a threat to the Senegalese Imamate of Futa Toro (then a French client state) with which the British were poised to interfere. The Ministry gave in and on 7 July 1878, a French force destroyed the Kaarta Toucouleur fort at Sabouciré, killing their leader, Almany Niamody. This portion of the Kaarta vassals was then incorporated into the Khasso protectorate kingdom.
