Mauretania Caesariensis

Mauretania Caesariensis was a Roman province in North Africa, established around 44 CE. It encompassed parts of modern-day western and central Algeria, north of the Atlas Mountains. Its capital was Caesarea (modern Cherchell, Algeria). Roman influence was primarily concentrated along the coast, with the vast interior often managed through local chieftains. The native inhabitants, known as the Mauri, were of Berber stock and were skilled light cavalrymen in the Roman legions. In the late 3rd century, a portion of Mauretania Caesariensis was separated to form the province of Sitifensis. The region saw significant Romanization, with coastal towns and roads developing, though mountainous areas remained less controlled. Christianity spread in the 4th and 5th centuries but was later suppressed by Arab conquests.123
