Saadi dynasty
Increasing power of the Mossi kingdoms resulted in larger conflicts with regional powers. The Kingdom of Yatenga became a key power attacking the Songhai Empire between 1328 and 1477 taking over Timbuktu and sacked the important trading post of Macina. When Askia Mohammad I became the leader of the Songhai Empire with the desire to spread Islam, he waged a holy war against the Mossi kingdoms in 1497. Although the Mossi forces were defeated in this effort, they resisted attempts to impose Islam. With the conquest of the Songhai by the Moroccans of the Saadi dynasty in 1591, the Mossi states reestablished their independence.
