Ahmadou Tall

Ahmadou Tall succeeded his father Umar Tall as ruler of the Toucouleur Empire after Umar's death. He faced immediate challenges from rival brothers and regional rebellions, weakening the empire's unity.

Ahmadou Tall signed a treaty with France at Nango, recognizing French protectorate status over parts of the Toucouleur Empire. The treaty ceded territory and trade rights, marking the beginning of French domination over the empire.

French forces captured the Toucouleur capital of Segou, forcing Ahmadou Tall to flee eastward. The loss of the capital effectively ended Toucouleur sovereignty and marked the collapse of the empire.

Ahmadou Tall died in exile in Sokoto after years of fleeing French forces. His death ended the last remnants of Toucouleur resistance and the dynasty founded by his father.
