At last Xerxes started for Europe at the head of the largest army ever seen, and we know the result of the expedition. After having witnessed the destruction of his fleet from the heights of Cape Colias, he fled precipitately, and returned to Asia Minor without waiting to see his troops routed on land. It is said that the victories of Salamis and Platæa saved Europe from barbarism. But this is unjust to both countries, as the Persians were not barbarians in the usual acceptation of the word, for, although, in some respects, they were less cultivated than the Greeks, in others they were superior to them and their culture was of an utterly different type. Moreover it is not saying much for the vitality and genius of Greece if its evolution could have been arrested by defeat and subjugation. The Hellenic race would have had to be utterly annihilated by the invasion of Asia, for Hellenic civilisation to have been exterminated. The Persians did not care about destroying whole nations, they only insisted on tribute and obedience, and then each country could do as it pleased. If Xerxes had been victorious, Hellas would have become a satrapy like Syria and Chaldea, and she would not have lost her characteristics any more than those countries did, but, like Egypt, she would soon have found an opportunity to recover her liberty. The Persian conquest would have changed the political course of Greek history, but it would have been powerless to arrest the general march of civilisation. The defeat of Xerxes resulted in his immediate retreat from the Persian frontier, but some of his garrisons were allowed to remain at Byzantium, till 478, at Eion, till 477; and at Doriscus till 450 and even later. But this concession was granted more as a sop to the pride of the Great King, than from any political or military necessity. Xerxes liked to think that he still had a foothold in Europe, so that he could recommence the war at any time, but Thessaly, Macedonia and Thrace soon ceased to recognise his authority and Athenian fleets now sailed menacingly where Phœnician vessels had hitherto had undisputed course. If Greece had been less disunited, and followed up her newly won advantages, all the colonies of Asia Minor would probably have shaken off the Asiatic yoke. But Sparta had no interest in distant enterprises, and Athens had enough to do to rebuild her walls and to organise her fleet, so Persia was spared an invasion.
And during all this time, whilst the fate of his empire hung in the balance, Xerxes was wasting what little courage and intelligence he had, in the intrigues and debauches of his harem. The war went on for twelve years without his attempting to make any effort to invade or even to prevent an invasion. About 466 an Athenian fleet cruising along the coasts of Caria and Lycia encountered the fleet of the Great King anchored at the mouth of the Eurymedon. It was another Mycale—the vessels were destroyed and the Athenian crews landed and routed the Persian army hard by. The conqueror then turned to Cyprus, scattered a second fleet of eighty sailing vessels, and returned to the Piræus laden with booty. Xerxes did not long survive this humiliation; he was assassinated by Aspamithres the eunuch and by Artabanus the captain of the guards in 465.
THE SUCCESSORS OF XERXES
[464-454 B.C.]
The same night the murderers went to the younger son, Artaxerxes, and after accusing another son, Darius, of the crime, they killed him under pretext of punishing the parricide. They then made an attempt on the life of Artaxerxes himself, but they were betrayed by one of their accomplices and executed. Then the sons of Artabanus, wishing to avenge their father, collected a force together, but they perished arms in hand. Hystaspes, the rightful heir to the throne, the eldest brother of the new king, who was in Bactriana at the death of Xerxes, now arrived at the head of an army to claim his rights, but he and his followers were defeated in 462 in two bloody battles.
