When the Romans landed in Africa, the Moors maintained a neutral stance, but after the quick Roman victories, most of their tribes pledged loyalty to the Empire. The most significant tribes were the Leuathae in Tripolitania, and the Frexi in Byzacena. The Frexi and their allies were led by Antalas, while other tribes in the area followed Cutzinas. The Aurasii (the tribes of the Aurès Mountains) in Numidia were ruled by Iaudas, and the Mauretanian Moors were led by Mastigas and Masuna.
