The Battle of Thermopylae took place when a small Greek alliance led by King Leonidas of Sparta attempted to block the advance of Xerxes' enormous Persian army through a narrow coastal pass. Although the Greeks were eventually overwhelmed after being outflanked, their resistance became legendary.

Thermopylae mattered not because it was a tactical victory, but because it became a lasting example of sacrifice, discipline, and resistance against overwhelming odds. The battle also bought time for Greek city-states to organize further defense.

Why It Matters

• Iconic stand of the Greek defenders
• Delayed the Persian advance
• Became a powerful symbol of courage and sacrifice
