Emirate of Trarza in the context of "Imamate of Futa Toro"

The Imamate of Futa Toro (Arabic: إمامة فوتة تورو; Fula: Imaama Futa Toro; French: Imamat de Futa Toro) was a West African theocratic monarchy of the Fula-speaking people (Fulɓe and Toucouleurs) in the middle valley of the Senegal River, in the region known as Futa Toro. Following the trend of jihads in the late 17th century and early 18th century, the religious leader Sulayman Bal led a jihad in 1776. His successor, the expansionist Abdul Kader defeated the emirates of Trarza and Brakna and by his death in 1806, power became decentralized between a few elite families of Torodbes. Threatened by both the expansion of the Toucouleur Empire and the French in the mid-19th century, Futa Toro was eventually annexed in 1859. By the 1860s, the power of the Almamy became nominal and the state was further weakened when a cholera epidemic killed a quarter of its population in 1868.
