From Bvio

'''Gallia Narbonensis''' was a Roman province located in what is now Provence in southern France. Bordering directly on Italy, control of the province gave the Roman state several advantages, such as control of the land route between Italy and the Iberian peninsula; a buffer against attacks on Italy by tribes from Gaul; and control of the lucrative trade routes of the Rhone valley, over which commercial goods flowed between Gaul and the trading center of Massalia. It became a province in 121 BC, originally under the name of '''Gallia Transalpina'''. The Romans called it ''Provinica Nostra'' ("our province") or simply ''Provincia'' ("the province"), a name which has survived in the modern name of the region. The name Gallia Narbonensis stems from the Roman colony of Narbo Martius (Narbonne) which was founded on the coast in 118 BC
