The growing power of the Cumaean Greeks led many indigenous tribes of the region to organise against them, notably the Dauni and Aurunci with the leadership of the Capuan Etruscans. This coalition was defeated by the Cumaeans in 524 BC under the direction of Aristodemus. The glorious victories of the colony increased its prestige, so much so that according to Diodorus Siculus, it was usual to associate the whole region of the Phlegraean Fields with Cumaean territory.
