Themistocles (ca. 528-462 B.C.), an Athenian political leader, was a brilliant commander and statesman who defeated Persia at sea and made Athens a great power.
Themistocles was the son of a middle-class Athenian father and a non-Athenian mother. Ability alone made him influential. He advocated resistance to Persia when some wanted appeasement, and he urged the development of Athens's navy when most trusted in its army. When elected chief magistrate in 493 B.C., he developed Piraeus for the first time as a naval base, and 10 years later, when his rivals had been eliminated by a series of ostracisms, he persuaded Athens to build a hundred warships from the profits of state-owned mines. When Persia invaded in 480 B.C., Athens had the largest navy in Greece. Themistocles insisted on using it fully at Artemisium and at Salamis, although his naval policy meant evacuating Athens and trusting in the "wooden walls" of its ships. He saw correctly that the liberty of Greece and the future of Athens depended on first defeating Persia at sea.
As representative of Athens on the Staff Council, Themistocles urged the Spartan commander of the Greek fleet to keep his advanced position in narrow waters at Salamis. When some captains wished to withdraw, Themistocles secretly informed Xerxes, the Persian king, of this dissension and advised him to attack, promising the aid of the Athenian fleet if he did attack. Xerxes attacked, thereby preventing the dispersal of the Greek fleet, and his much larger fleet was decisively defeated in the narrow waters by the ramming tactics of the Greek squadrons. Themistocles proposed that the Greeks sail to the Dardanelles, destroy the Persian pontoon bridge there, and cut the army's lines of supply and cause it to withdraw. The proposal was defeated, but he sent information of it to Xerxes, adding that he himself was responsible for its defeat.
Themistocles worked next for the rise of Athens at the expense of Sparta. He used his popularity as victor of Salamis to lull Sparta's suspicions as Athens rebuilt its fortifications in 479-478 B.C. against Sparta's wishes, and he openly opposed Sparta's ambitions in northern Greece. His plans for making Athens supreme at sea were implemented when Athens displaced Sparta in the command of the allied fleet, and his faith in democracy was put into effect by the rule of Pericles. But Themistocles himself fell out of favor. He was ostracized, probably in 472 B.C., and then exiled and condemned to death on a charge of being in Persia's pay. He made a dramatic escape to Persia, where he was appointed governor of Magnesia in Asia Minor. The Greek historian Thucydides said that Themistocles died a natural death, though some reported suicide. Later a tomb was built at Piraeus in honor of Themistocles's achievements. The salvation of Greece and the stature of Athens give the true measure of his greatness.
