Djolof
In 1549, Kayor successfully broke from the Jolof Empire under the leadership of the crown prince Amari Ngoone Sobel Fall. The breakaway state of Cayor used its direct access to European trade (Jolof was landlocked and had no port) to grow in wealth and power. Kayor invaded its southern neighbor, Bawol, and began forming a personal union of its own. It defeated its overlord at the Battle of Danki in 1549. The battle caused a ripple effect resulting in other states leaving the empire. By 1600, the Jolof Empire was effectively over. Jolof was reduced to a kingdom; nevertheless, the title of Burba remained associated with imperial prestige and commanded nominal respect from its ancient vassals.
