A narrow coastal pass allowed a small Greek force to confront an enormous Persian army and create one of history’s most famous last stands.
Historical Event: Battle of Thermopylae
Date: 480 BCE
Location: Thermopylae, Greece
King Xerxes I invaded Greece with a massive Persian army during the second Persian invasion.
A Greek coalition chose the narrow pass at Thermopylae as a defensive position because the terrain limited how many Persian troops could attack at one time.
King Leonidas of Sparta commanded the Greek force.
Although popular tradition focuses on the famous 300 Spartans, several thousand other Greek soldiers also participated during the battle.
For two days, Greek hoplites repeatedly resisted Persian attacks.
Their heavy shields, long spears, disciplined formations, and knowledge of the narrow terrain reduced the Persian numerical advantage.
The situation changed when the Persians learned of a mountain path that could take troops around the Greek position.
Realizing that his army was about to be surrounded, Leonidas dismissed many of the remaining Greeks.
The Spartans stayed, together with forces including Thespians and Thebans.
They fought a final action and were overwhelmed.
Thermopylae was a Persian victory, but the resistance became a powerful symbol throughout Greece.
The invasion continued, yet later Greek victories at Salamis and Plataea helped defeat the Persian campaign.
The surprising part is that Thermopylae became famous not because the defenders won, but because they knowingly remained in an almost impossible position.
A narrow strip of land beside the sea turned numbers into a temporary disadvantage and allowed a relatively small defensive force to delay one of the largest armies of the ancient world.
