By the mid-2nd century BC, Rome was trading heavily with the Greek colony of Massalia (modern Marseille) on the southern coast of Gaul. Massalia, founded by colonists from Phocaea, was by this point centuries old and quite prosperous. Rome entered into an alliance with Massalia, by which it agreed to protect the town from local Gauls, nearby Aquitani, sea-borne Carthaginians and other rivals, in exchange for a small strip of land that it wanted in order to build a road to Hispania, to assist in troop transport. The Massalians, for their part, cared more for their economic prosperity than they did for territorial integrity.
