Mastinas (Mastigas) — Moorish Ruler of Mauretania Caesariensis
Procopius of Caesarea records Mastinas as one of the major Moorish rulers of 6th-century North Africa. In one passage, Procopius says Mastinas and Iaudas had planned to drive Ortaïas and the Moors under him from the land “where they had dwelt from of old.” In another, he describes Mastigas as controlling almost all of Mauretania Caesariensis, except the Roman-held city of Caesarea. Scholars generally treat Mastinas and Mastigas as the same ruler or as manuscript variants of the same name.
That makes Mastinas a significant Moorish power in northern Algeria, ruling in the former Roman province of Mauretania Caesariensis.
📍 Modern location: broadly northern Algeria, with Caesarea corresponding to modern Cherchell, west of Algiers.
