Iberian civilisation, which developed during the second Iron Age, is one of the most important western Mediterranean civilisations. The Greeks and Romans gave the name Iberian to all the peoples living around the river Iberus and, by extension, to all the peoples living in a wide area between Marseille and Gibraltar. The Iberians were a diverse group with common cultural characteristics. Like other Mediterranean peoples of the time (Greeks, Phoenicias, Etruscans,...), they possessed a developed and complex civilisation with urban and trade networks.
