Moulouya River
As Carthaginian power waned, the influence of Berber leaders in the hinterland grew. By the 2nd century BCE, several large but loosely administered Berber kingdoms had emerged. Two of them were established in Numidia, behind the coastal areas controlled by Carthage. West of Numidia lay Mauretania, which extended across the Moulouya River in Morocco to the Atlantic Ocean.
