I. XERXES I., son of Darius I. and Atossa, the daughter of Cyrus the Great, and therefore appointed successor to his father in preference to his eldest half-brothers, who were born before Darius had become king (Herod. vii. 2 f.). After his accession in October 485 B.C. he suppressed the revolt in Egypt which had broken out in 486, appointed his brother Achaemenes as satrap and "brought Egypt under a much heavier yoke than it had been before" (Herod. vii. 7). His predecessors, especially Darius, had not been successful in their attempts to conciliate the ancient civilizations. This probably was the reason why Xerxes in 484 abolished the "kingdom of Babel" and took away the golden statue of Bel (Marduk, Merodach), the hands of which the legiti mate king of Babel had to seize on the first day of each year, and killed the priest who tried to hinder him'. Therefore Xerxes does not bear the title of "King of Babel" in the Babylonian docu ments dated from his reign, but "King of Persia and Media," or simply "King of countries" (i.e., of the world). This proceeding led to two rebellions, probably in 484 and 479; in the Babylonian documents occur the names of two ephemeral kings, Shamash irba, and Tarziya, who belong to this time. One of these rebellions was suppressed by Megabyzus, son of Zopyrus, the satrap whom the Babylonians had slain'.
Darius had left to his son the task of punishing the Greeks for their interference in the Ionian rebellion and the victory of Mara thon. From 483 Xerxes prepared his expedition with great care : a channel was dug through the isthmus of the peninsula of Mount Athos; provisions were stored in the stations on the road through Thrace ; two bridges were thrown across the Hellespont. Xerxes concluded an alliance with Carthage, and thus deprived Greece of the support of the powerful monarchs of Syracuse and Agrigen tum. Many smaller Greek states, moreover, took the side of the Persians ("Medized"), especially Thessaly, Thebes and Argos. A large fleet and a numerous army were gathered. In the spring of 48o Xerxes set out from Sardis. At first Xerxes was victorious everywhere. The Greek fleet was beaten at Artemisium,
Thermopylae stormed, Athens conquered, the Greeks driven back to their last line of defence at the Isthmus of Corinth and in the Bay of Salamis. But Xerxes was induced by the astute message of Themistocles (against the advice of Artemisia of Halicar nassus) to attack the Greek fleet under unfavourable conditions, instead of sending a part of his ships to the Peloponnesus and awaiting the dissolution of the Greek armament'. The battle of Salamis (Sept. 28,48o) decided the war. (See SALAMIS.) Having lost his communication by sea with Asia, Xerxes was forced to retire to Sardis ; the army which he left in Greece under Mar donius was in 479 beaten at Plataea (q.v.). The defeat of the Persians at Mycale roused the Greek cities of Asia.
Of the later years of Xerxes little is known. He sent out Sataspes to attempt the circumnavigation of Africa (Herod. iv. 143), but the victory of the Greeks threw the empire into a state of languid torpor, from which it could not rise again. The king himself became involved in intrigues of the harem (cf. Herod. ix. 1o8 ff.—compare the late Jewish novel of Esther, in which a remembrance of the true character of the king is retained) and was much dependent upon courtiers and eunuchs. He left inscrip tions at Persepolis, where he added a new palace to that of Darius, at Van in Armenia, and on Mount Elvend near Ecbatana ; in these 'Herod. i. 183, by Ctesias changed into a plundering of the tomb of Belitanas or Belus: cf. Aelian, Var. Hist. 13, 3 ; Aristobulus ap. Arrian vii. 17, 2, and Strabo xvi., p. 738.
