Key Takeaways
- Leonidas was a king of Sparta who fought at the Battle of Thermopylae.

- He and his men fought to the death, buying time for the Greek cause.
- His last stand became one of history's most famous symbols of courage.
Few last stands in history are remembered like that of Leonidas I. At a narrow mountain pass called Thermopylae, the Spartan king and a small band of Greeks faced the largest army the ancient world had ever assembled — and refused to yield.
The stand of the 300
In 480 BC, as Xerxes I poured his vast Persian host into Greece, Leonidas held the pass with about 300 Spartans and thousands of allies. For days they blocked the way, until a betrayal let the Persians outflank them. Leonidas sent most of the Greeks away and stayed with his Spartans to fight to the death.
An immortal sacrifice
The defenders were killed, but their stand bought time and steeled Greek resolve — soon after, Themistocles destroyed the Persian fleet at Salamis. From Sparta of classical Greece, Leonidas became, and remains, the ancient world’s supreme symbol of courage against impossible odds.
Influence
Leonidas's death at Thermopylae turned a military defeat into an immortal symbol of free people resisting tyranny against impossible odds.
Legacy
His stand has inspired soldiers, poets and filmmakers for 2,500 years as the very emblem of courage and sacrifice.
