Provinces · The later western provinces
LW-58 Mauretania Caesariensis

The reduced province retained ports, towns, agricultural resources, and a difficult interior political geography. Military security depended upon auxiliary traditions, local recruitment, routes, and relationships with regional leaders. Christian institutions developed within a provincial society still marked by substantial cultural variety.
Fourth-century revolt and later imperial weakness exposed the limits of central authority. Vandal and local control differed across districts, and Eastern Roman recovery was selective. The province’s late history consequently cannot be represented by one uninterrupted block of territory changing sovereigns as a whole. Its name endured within a more fragmented coastal and inland world.
