Carthage was Palermo’s major trading partner under the Phoenicians and the city enjoyed a prolonged peace during this period. Palermo came into contact with the Ancient Greeks between the 6th and the 5th centuries BC which preceded the Sicilian Wars, a conflict fought between the Greeks of Syracuse and the Phoenicians of Carthage for control over the island of Sicily. During this war the Greeks named the settlement Panormos (Πάνορμος) from which the current name is derived, meaning "all port" due to the shape of its coast. It was from Palermo that Hamilcar I's fleet (which was defeated at the Battle of Himera) was launched. In 409 B.C. the city was looted by Hermocrates of Syracuse. The Sicilian Wars ended in 265 BC when Carthage and Syracuse stopped warring and united in order to stop the Romans from gaining full control of the island during the First Punic War. In 276 BC, during the Pyrrhic War, Panormos briefly became a Greek colony after being conquered by Pyrrhus of Epirus, but returned to Phoenician Carthage in 275. In 254 BC Panormos was besieged and conquered by the Romans in the first battle of Panormus (the name Latin name). Carthage attempted to reconquer Panormus in 251 BC but failed.
