Massalia (Greek: Μασσαλία, romanized: Massalía; Latin: Massilia) was an ancient Greek colony (apoikia) on the Mediterranean coast, east of the Rhône. Settled by the Ionians from Phocaea in 600 BC, this apoikia grew up rapidly, and its population set up many outposts for trading in modern-day Spain, Corsica and Liguria. Massalia persisted as an independent colony until the Roman campaign in Gaul in the 1st Century BC. The ruins of Massalia still exist in the contemporary city of Marseille, which is considered the oldest city of France and one of Europe's oldest continuously inhabited settlements.[1]
