Marseille was founded in 600 B.C. by Greeks from Phocaea as a trading port under the name Μασσαλία (Massalia; see also List of traditional Greek place names). Facing an opposing alliance of the Etruscans, Carthage and the Celts, the Greek colony allied itself with the expanding Roman Republic for protection. The association with the expanding Roman market saw the city thrive by acting as a link between the interior of Gaul, hungry for Roman goods and wine (of which Massilia was steadily exporting by 500 B.C.), and Rome's insatiable slave markets. Under this arrangement the city maintained its independence until the rise of Julius Caesar, when it joined the losing side in civil war, and lost its independence. It was the site of a siege and naval battle. During the Roman times, it was called Massilia.
