Thermopylae: Why 300 Spartans Refused to Run (480 BC)

The Immortals died in front of their own king. In 480 BC, Xerxes of Persia marched 100,000 soldiers into a pass fifteen meters wide. He expected to crush 300 Spartans by sundown. Within two days, his elite Immortals had been hurled out of the pass twice and his own brothers lay dead in the dust. This is the story of how 300 Spartans and 6,700 forgotten allies proved that terrain, discipline, and unbreakable will could destroy the largest empire the ancient world had ever assembled. And why every war college on earth — from West Point to Sandhurst — still teaches the lesson of Thermopylae today. ⚠️ This video contains AI-generated historical reconstructions based on primary historical sources (Herodotus VII–VIII, Diodorus Siculus XI) and modern scholarly accounts.
