Numidia

Numidia, originally the Massylii, was the ancient kingdom of Numidians, split between the Massylii and the Masaesyli. Initially allied to Carthage, the Massylii turned to Rome when it became clear that war was lost, and united Numidia in the process. After which, Numidia existed as a Roman protectorate before they sided with the Pompeians, and in retaliation, were annexed by the Caesarians to the Roman Republic.
