When his chief rival Aristides was ostracized, Themistocles gained power in Attica. In 483 Themistocles persuaded the Athenians to spend their new-found wealth from silver mines to strengthen their naval force and build triremes. In 480 General Themistocles led an Athenian naval force and played a decisive role in the Battle of Salamis.
After the Persian War, in 476, Themistocles, as chorus-leader, won first prize in an Athenian production of a tragedy of Phrynicus. Themistocles was ostracized soon after (between 476-471). He was proclaimed a traitor and fled to Asia Minor where the Persians, against whom Themistocles had formerly fought, received him and granted him a livelihood.
