The largest groups inhabiting the Iberian Peninsula before the Roman conquest were the Iberians and the Celts. The Iberians inhabited the Mediterranean side of the peninsula, from the northeast to the southeast. The Celts inhabited much of the inner and Atlantic sides of the peninsula, from the northwest to the southwest. Basques occupied the western area of the Pyrenees mountain range and adjacent areas, the Phoenician-influenced Tartessians culture flourished in the southwest and the Lusitanians and Vettones occupied areas in the central west. Several cities were founded along the coast by Phoenicians, and trading outposts and colonies were established by Greeks in the East. Eventually, Phoenician-Carthaginians expanded inland towards the meseta; however, due to the bellicose inland tribes, the Carthaginians got settled in the coasts of the Iberian Peninsula.
