Leonidas I (c. 540-480 BCE) was a king of Sparta who led a small Greek force, including his famous 300 Spartans, in a legendary last stand against the massive Persian army of Xerxes I at the Battle of Thermopylae in 480 BCE. His sacrifice gave the Greek city-states time to organize their defense and ultimately defeat the Persian invasion.

In 480 BCE, Xerxes I invaded Greece with an army estimated at hundreds of thousands. Leonidas and approximately 7,000 Greeks held the narrow coastal pass of Thermopylae for three days.
