The Battle of Thermopylae was fought in 480 BC between the Achaemenid Persian Empire under Xerxes I and an alliance of Greek city-states led by Sparta under Leonidas I. Lasting over the course of three days, it was one of the most prominent battles of both the second Persian invasion of Greece and the wider Greco-Persian Wars.

The Achaemenid Empire or Achaemenian Empire, also known as the First Persian Empire, was the ancient Iranian empire founded by Cyrus the Great of the Achaemenid dynasty in 550 BC. Based in modern-day Iran, it was the largest empire by that point in history, spanning a total of 5.5 million square kilometres. The empire spanned from the Balkans and Egypt in the west, West Asia as the base, the majority of Central Asia to the northeast, and the Indus Valley to the southeast.
