The Battle of Thermopylae (/θərˈmɒpɨliː/ thər-MOP-i-lee; Greek: Μάχη τῶν Θερμοπυλῶν, Machē tōn Thermopylōn) was fought between alliances of Greek city-states, led by King Leonidas of Sparta, and the Persian Empire of Xerxes I over the course of three days, during the second Persian invasion of Greece. It took place simultaneously with the naval battle at Artemisium, in August or September 480 BC, at the narrow coastal pass of Thermopylae ("The Hot Gates"). The Persian invasion was a delayed response to the defeat of the first Persian invasion of Greece, which had been ended by the Athenian victory at the Battle of Marathon in 490 BC. Xerxes had amassed a huge army and navy, and set out to conquer all of Greece.
