Songhai Empire
The Askiya Dynasty, also known as the Askia Dynasty, ruled the Songhai Empire at the height of that state's power. It was founded in 1493 by Askia Mohammad I, a general of the Songhai Empire who usurped the Sonni Dynasty. The Askiya ruled from Gao over the vast Songhai Empire until its defeat by a Moroccan invasion force in 1591. After the defeat, the dynasty moved south back to its homeland and created several smaller kingdoms in what is today Songhai in south-western Niger and further south in the Dendi.
