The first known inhabitants of this region were hunter-gatherers and it was later occupied by pastoralists, shepherds living in caves or simple huts. It later came under the control of a Gaulish tribe called Vellavi and at the time of Julius Caesar's Gallic Wars, this area lay on the border of Gallia Narbonensis. The area became a Roman province in 121 BC, originally under the name "Gallia Transalpina" (Transalpine Gaul). The name distinguished it from Cisalpine Gaul on the near side of the Alps to Rome. In 40 BC, during the Second Triumvirate, Lepidus was given responsibility for Narbonese Gaul (along with Hispania and Africa), while Mark Antony was given the balance of Gaul.
