of the Greek cities to start to expand their territories again, ultimately leading to the events known as the "First Sicilian War". Carthage joins the fight Carthage and Elymians joined hands in 510 BC to oppose the expedition of Prince Dorieus, who had lost the Spartan throne and was seeking to found a colony, showed up to colonize Eryx – after being expelled from Libya by Carthage in 511 BC. Dorieus was defeated and killed; the Greek survivors then founded Heraclea Minoa. Sicilian Greeks (probably the cities of Akragas, Gela and Selinus) fought an undated war of revenge against Carthage, which led to the destruction of Minoa and a treaty which brought economic benefits for the Greeks. An appeal for aid to avenge the death of Dorieus was ignored by mainland Greece, even by Leonidas of Sparta, brother of Dorieus and who later would win immortal fame at Thermopylae in 480 BC. This possibly demonstrated the futility of opposing Carthage by single Greek cities or the unreliability of aid from mainland Greece, a situation that would change with the rise of the Greek tyrants in Sicily. Greek tyrants While Carthage remained engaged in Sardinia after 510 BC, most of the Greek colonies in Sicily fell under the rule of tyrants. The tyrants of Gela, Akragas and Rhegion successfully expanded their dominion at the expense of native Sicilians and other Greek cities during 505–480 BC, with the Dorian city of Gela being the most successful. Dorian Greeks dominate Sicily Cleander (505–498 BC) and his brother Hippocrates (498–491) of Gela successfully took over both Ionian and Dorian Greek territory, and by 490 BC, Zankle, Leontini, Catana, Naxos, besides neighboring Sicel lands and Camarina had fallen to Gela. Gelo, successor of Hippocrates, captured Syracuse and made the city his capital. By using ethnic cleansing, deportation and enslavement, Gelo transformed the former Ionian cities into Dorian ones and made Syracuse the dominant power in Sicily. Meanwhile, Akragas, another Doric city, had taken over neighboring Sikan and Sicel lands under the tyrant Theron (488–472 BC). To forestall any conflicts between Akragas and Syracuse, Gelo and Theron married into each other's families, thus creating a united front against the Sicels and Ionian Greeks of Sicily. Ionian Greeks call on Carthage To counter this Doric threat, Anaxilas of Rhegion from Italy, who had captured Zankle from Gela in 490 BC, allied himself with Terillus of Himera, and
