Jolof
Jolof was a Wolof state in what is now northern Senegal. Tradition credited its founding to Ndiadiane Ndiaye, who united local chiefs; in 1337 Jolof was a vassal of Mali.
By the late fourteenth century Jolof was independent, and its buurba received tribute from Cayor, Baol and Waalo. In 1549 Cayor's ruler killed buurba Leele Fuli Fak at Danki, breaking the confederation and leaving Jolof cut off from coastal trade. It repelled a Mauritanian marabout invasion around 1670, but civil wars followed; around 1820 its ruler agreed to pay tribute to the Trarza Moors after their slave raids.
