Thermopylae (lit. hot gates) was a pass the Greeks tried to defend in battle against the Persian forces led by Xerxes, in 480 B.C. The Greeks (Spartans and allies) knew they were outnumbered and hadn't a prayer, so it was no surprise that the Persians won the Battle of Thermopylae.
In 479 BC, the Athenians and Spartans, with their allies, defeated the Persian army at the Battle of Plataea. However, it was Athens that took the war to Asia Minor. These victories enabled it to bring most of the Aegean and many other parts of Greece together in the Delian League, an Athenian-dominated alliance.
