Moulouya River
In the Mercenary War (241-238 BC), a rebellion was instigated by mercenary soldiers of Carthage and African allies. Berber soldiers participated after being unpaid following the defeat of Carthage in the First Punic War. Berbers succeeded in obtaining control of much of Carthage's North African territory, and they minted coins bearing the name Libyan, used in Greek to describe natives of North Africa. The Carthaginian state declined because of successive defeats by the Romans in the Punic Wars; in 146 BC the city of Carthage was destroyed. As Carthaginian power waned, the influence of Berber leaders in the hinterland grew. By the 2nd century BC, 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. The high point of Berber civilization, unequaled until the coming of the Almohads and Almoravid dynasty more than a millennium later, was reached during the reign of Masinissa in the 2nd century BC. After Masinissa's death in 148 BC, the Berber kingdoms were divided and reunited several times. Masinissa's line survived until 24 AD, when the remaining Berber territory was annexed to the Roman Empire.
