Mastigas or Mastinas ruled the Mauro-Roman Kingdom during the sixth century as King of the Moors and Romans, succeeding Masuna. During the reign of Mastigas, the Mauro-Roman Kingdom governed almost the entire ancient Roman province of Mauretania Caesariensis, except for the former capital of Caesarea which was held by the Eastern Roman Empire.

The Mauro-Roman Kingdom was an independent Christian Berber kingdom centered on the city of Altava which controlled much of the ancient Roman province of Mauretania Caesariensis, located in present-day northern Algeria. The kingdom was first formed in the fifth century as Roman control over the province weakened and Imperial resources had to be concentrated elsewhere, notably in defending the Italian Peninsula itself from invading Germanic tribes.

The Quinquegentiani were a Classical Age Berber tribal confederation inhabiting the lands between the cities of Saldae and Rusuccuru, a region which is now known as Kabylia. Their territory laid at the eastern border of the Roman province of Mauretania Caesariensis, and although they were officially under Roman rule, they acted very autonomously.
