474 BC

Hiero I, Tyrant of Sicily, allied with Aristodemus, the Tyrant of Cumae, defeat the Etruscan navy in the Battle of Cumae as the Etruscan try to capture the Greek city of Cyme (Cumae) in Italy. This victory marks the end of Etruscan aggression against the Greeks in southern Italy and saves the Greeks of Campania from Etruscan domination.
