Gelo was succeeded by his brother Hiero, who fought against the Etruscans at Cumae in 474 BC. His rule was eulogized by poets like Simonides of Ceos, Bacchylides and Pindar, who visited his court. A democratic regime was introduced by Thrasybulos (467 BC). The city continued to expand in Sicily, fighting against the rebellious Siculi, and on the Tyrrhenian Sea, making expeditions up to Corsica and Elba. In the late 5th century BC, Syracuse found itself at war with Athens, which sought more resources to fight the Peloponnesian War. The Syracusans enlisted the aid of a general from Sparta, Athens' foe in the war, to defeat the Athenians, destroy their ships, and leave them to starve on the island (see Sicilian Expedition). In 401 BC, Syracuse contributed a force of 300 hoplites and a general to Cyrus the Younger's Army of the Ten Thousand.
