Numidians
The Numidians were the Berber people who lived in Numidia (present day Algeria) and in a smaller part of Tunisia. The Numidians were one of the earliest natives to trade with the settlers of Carthage. As Carthage grew, the relationship with the Numidians blossomed. Carthage's military used the Numidian cavalry as mercenaries. Numidia provided some of the highest quality cavalry of the Second Punic War, and the Numidian cavalry played a key role in a number of battles, both early on in support of Hannibal and later in the war after switching allegiance to the Roman Republic.
The Punic Wars
During the Second Punic War, Syphax was the king of the largest Numidian kingdom, the Masaesyli. In 213 BC, Syphax ended his alliance with Carthage. In 208 BC, he rejoined after marrying Sophonisba, daughter of Hasdrubal Gisco.
Syphax tried to get Hannon Barca and Publius Cornelius Scipio to bring peace between the two nations after the Romans had landed in Africa. With the help of Masinissa, Publius Scipio's troops set fire to Syphax's camp.
