A war with Hellenic Massalia followed. Carthage lost battles but managed to safeguard Phoenician Spain and close the Strait of Gibraltar to Greek shipping, while Massalians retained their Spanish colonies in Eastern Iberia above Cape Nao. Southern Spain was closed to Greeks. Carthaginians in support of the Phoenician colony of Gades in Spain also brought about the collapse of Tartessos in Spain by 530 BC, either by armed conflict or by cutting off Greek trade. Carthage also besieged and took over Gades at that time. The Persians had taken over Cyrene by then, and Carthage may have been spared a trial of arms against the Persian Empire when the Phoenicians refused to lend ships to Cambyses in 525 BC for an African expedition. Carthage may have paid tribute irregularly to the Great King. It is not known if Carthage had any role in the Battle of Cumae in 524 BC, after which Etruscan power began to wane in Italy.
