Bambara people
Umar Tall returned to Senegal in 1845, where he began preaching Islam among the Toucouleur people. Umar Tall obtained weapons from Europe, then mobilized the Toucouleur to pursue an Islamic holy war in 1854 against the non-Muslim ethnic groups and those Muslims who had strayed. The Toucouleur armies succeeded. The Toucouleur Empire grew and extended from Senegal to much of Mali over the next ten years. His son Mustafa reigned over this empire and Teucouleur people between 1864 and 1870, followed by Umar Tall's second son named Ahmadu Seku. The rule of Ahmadu Seku, state Gallieni and Joffre, was a "Toucouleur-Muslim despot" over the Mandinka people and Bambara people. The empire collapsed in the 1880s as the Fulani, Tuaregs and the Moors attacked the Toucouleurs, and a civil war between local Toucouleur leaders engulfed the region. The empire ended in 1891, after the French colonial forces invaded the region.
