To place oneself in front of his/her nation is the ultimate testament of courage
Leonidas (c. 530-480 B.C.) was a king of the city-state of Sparta from about 490 B.C. until his death at the Battle of Thermopylae against the Persian army in 480 B.C. Although Leonidas lost the battle, his death at Thermopylae was seen as a heroic sacrifice because he sent most of his army away when he realized that the Persians had outmaneuvered him. Three hundred of his fellow Spartans stayed with him to fight and die. Almost everything that is known about Leonidas comes from the work of the Greek historian Herodotus (c. 484-c. 425 B.C.).
Battle of Thermopylae
Under Xerxes I, the Persian army moved south through Greece on the eastern coast, accompanied by the Persian navy moving parallel to the shore. To reach its destination at Attica, the region controlled by the city-state of Athens, the Persians needed to go through the coastal pass of Thermopylae (or the “Hot Gates,” so known because of nearby sulfur springs). In the late summer of 480 B.C., Leonidas led an army of 6,000 to 7,000 Greeks from many city-states, including 300 Spartans, in an attempt to prevent the Persians from passing through Thermopylae.
Leonidas established his army at Thermopylae, expecting that the narrow pass would funnel the Persian army toward his own force. For two days, the Greeks withstood the determined attacks of their far more numerous enemy. Leonidas’ plan worked well at first, but he did not know that there was a route over the mountains to the west of Thermopylae that would allow the enemy to bypass his fortified position along the coast. A local Greek told Xerxes about this other route and led the Persian army across it, enabling them to surround the Greeks. Much of the Greek force retreated rather than face the Persian army. An army of Spartans, Thespians and Thebans remained to fight the Persians. Leonidas and the 300 Spartans with him were all killed, along with most of their remaining allies. The Persians found and beheaded Leonidas’ corpse–an act that was considered to be a grave insult.
After the Battle
Leonidas’ sacrifice, along with that of his Spartan hoplites, did not prevent the Persians from moving down the Greek coast into Boeotia. In September 480 B.C., however, the Athenian navy defeated the Persians at the Battle of Salamis, after which the Persians returned home. Nonetheless, Leonidas’ action demonstrated Sparta’s willingness to sacrifice itself for the protection of the Greek region.
Leonidas achieved lasting fame for his personal sacrifice. Hero cults were an established custom in ancient Greece from the eighth century B.C. onward. Dead heroes were worshipped, usually near their burial site, as intermediaries to the gods. Forty years after the battle, Sparta retrieved Leonidas’ remains (or what were believed to be his remains) and a shrine was built in his honor.
