Neapolis was a Greek city-state in Magna Graecia that is now known as Naples, a city in southern Italy. Neapolis was founded by Euboean settlers as Phaleron, named for one of the Argonauts, and the new city of Parthenope (named for one of the sirens who failed to bewitch Odysseus with her song) was founded during the 8th century BC. The city-state survived the Etruscan expansion of the 500s BC, and it was refounded as Neapolis in 470 BC, having previously been pushed to the commercial margins by the Etruscans. The city allied with the Roman Republic in 327 BC, and it was pushed into its sphere of influence, eventually being annexed.
