Djolof
The Kingdom of Jolof ( or '), also known as Wolof and Wollof"', was a West African rump state located in what is today the nation of Senegal. For nearly two hundred years, the Wolof rulers of the Jolof Empire collected tribute from vassal kings states who voluntarily agreed to the confederacy. At the Battle of Danki, the Buurba Jolof was defeated by the lord of Kayor resulting in the rapid disintegration of the empire. Jolof survived as a meager state, unable to prosper from the Atlantic trade between its former vassal territories and the Portuguese.
