The collapse of the Western Roman Empire led to the establishment of a native Kingdom based in Altava (modern day Algeria) known as the Mauro-Roman Kingdom. It was succeeded by another Kingdom based in Altava, the Kingdom of Altava. During the reign of Kusaila its territory extended from the region of modern day Fez in the west to the western Aurès and later Kairaouan and the interior of Ifriqiya in the east.
