Which Persian king is notable for his failed invasion of Greece in 480 BC?
Xerxes I, called Xerxes the Great, was the fifth king of kings of the Achaemenid dynasty of Persia. Like his father and predecessor Darius I, he ruled the empire at its territorial apex. He ruled from 486 BC until his assassination in 465 BC at the hands of Artabanus, the commander of the royal bodyguard.
Xerxes I is notable in Western history for his failed invasion of Greece in 480 BC. His forces temporarily overran mainland Greece north of the Isthmus of Corinth until losses at Salamis and Plataea a year later reversed these gains and ended the second invasion decisively. However, Xerxes successfully crushed revolts in Egypt and Babylon. Roman Ghirshman says that, "After this he ceased to use the title of 'king of Babylon', calling himself simply 'king of the Persians and the Medes'." Xerxes also oversaw the completion of various construction projects at Susa and Persepolis.
Xerxes is one of the Persian kings identified as Ahasuerus in the biblical Book of Esther.
