Xerxes I (commonly known as Xerxes the Great; c. 518 BC – 465 BC) was a Persian ruler who reigned as the fourth King of Kings of the Achaemenid Empire, reigning from 486 BC until his assassination in 465 BC. He was the son of Darius the Great and Atossa, a daughter of Cyrus the Great.
In Western history, Xerxes is best known for his invasion of Greece in 480 BC, which ended in Persian defeat. Xerxes was made successor by Darius over his elder brother Artobazan and inherited a large, multi-ethnic empire upon his father's death. He consolidated power by crushing revolts in Egypt and Babylon, and renewed his father's campaign to subjugate Greece and punish Athens and its allies for their interference in the Ionian Revolt.
