The Numidians were semi-nomadic Berber tribes who lived in Numidia, in Algeria east of Constantine and in part of Tunisia and Morocco. 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. Numidians are also very useful in representing more auxiliaries in a Roman Army - or with a small amount of conversion work they would make fantastic Greek Light Infantry.
