In the Battle of Thermopylae of 480 BC, an alliance of Greek city-states fought the invading Persian army at the pass of Thermopylae in central Greece. Vastly outnumbered, the Greeks held back the enemy in one of the most famous last stands of history.
The subsequent Greek victory in the Battle of Salamis left much of the Persian navy destroyed. Xerxes was forced to flee to Asia and left his army in Greece under Mardonius, who was to meet the Greeks in battle for one last time. The Spartans and other Greek allies assembled at full strength and decisively defeated the Persians in the Battle of Plataea, putting an end to the Greco-Persian War.
The performance of the defenders at the battle of Thermopylae is often used as an example of the advantages of training, equipment and good use of terrain to maximize an army's potential, as well as a symbol of courage against overwhelming odds. The heroic sacrifice of the Spartans and the Thespians has captured the minds of many throughout the ages and has given birth to many cultural references as a result.
