The circumstances which caused a renewal of Greek agressions upon Asia towards the close of the reign of Xerxes are not very clearly narrated by the authors who speak of them. It appears, however, that after twelve years of petty operations, during which Eion was recovered, and Doriscus frequently attacked, but without effect, the Athenians resolved, in B.C. 466, upon a great expedition to the eastward. Collecting a fleet of 300 vessels, which was placed under the command of Cimon, the son of Miltiades, they sailed to the coast of Caria and Lycia, where they drove the Persian garrisons out of the Greek towns, and augmenting their navy by fresh contingents at every step, proceeded along the shores of Pamphylia as far as the mouth of the river Eurymedon, where they found a Phoenician fleet of 340 vessels, and a Persian army, stationed to protect the territory. Engaging first the fleet they defeated it, and drove it ashore, after which they disembarked and gained a victory over the Persian army. As many as two hundred triremes were taken or destroyed. They then sailed on towards Cyprus, where they met and destroyed a squadron of eighty ships, which was on its way to reinforce the fleet at the Eurymedon. Above a hundred vessels, 20,000 captives, and a vast amount of plunder were the prize of this war; which had, however, no further effect on the relations of the two powers. In the following year the reign of Xerxes came to an end abruptly. With this monarch seems to have begun those internal disorders of the seraglio, which made the Court during more than a hundred and forty years a perpetual scene of intrigues, assassinations, executions, and conspiracies. Xerxes, who appears to have only one wife, Amestris, the daughter (or grand-daughter) of the conspirator, Otanes, permitted himself the free indulgence of illicit passion among the princesses of the Court, the wives of his own near relatives. The most horrible results followed. Amestris vented her jealous spite on those whom she regarded as guilty of stealing from her the affections of her husband; and to prevent her barbarities from producing rebellion, it was necessary to execute the persons whom she had provoked, albeit they were near relations of the monarch. The taint of incontinence spread among the members of the royal family; and a daughter of the king, who was married to one of the most powerful nobles, became notorious for her excesses. Eunuchs rose into power, and fomented the evils which prevailed. The king made himself bitter enemies among those whose position was close to his person. At last, Artabanus, chief of the guard, a courtier of high rank, and Aspamitres, a eunuch, who held the office of chamberlain, conspired against their master, and murdered him in his sleeping apartment, after he had reigned twenty years.
