(M194) The usurper proved a tyrant. A conspiracy of Persians followed, headed by the descendants of Cyrus; and Darius, the chief of these—the son of Hystaspes, became king of Persia, after Smerdis had reigned seven months. But this reign, brief as it was, had restored the old Magian priests to power, who had, by their magical arts, great popularity with the people, not only Medes, but Persians. (M195) Darius restored the temples and the worship which the Magian priests had overthrown, and established the religion of Zoroaster. The early years of his reign were disturbed by rebellions in Babylonia and Media, but these were suppressed, and Darius prosecuted the conquests which Cyrus had begun. He invaded both India and Scythia, while his general, Megabazus, subdued Thrace and the Greek cities of the Hellespont. (M196) The king of Macedonia acknowledged the supremacy of the great monarch of Asia, and gave the customary present of earth and water. Darius returned at length to Susa to enjoy the fruit of his victories, and the pleasures which his great empire afforded. For twenty years his glories were unparalleled in the East, and his life was tranquil. (M197) But in the year B.C. 500, a great revolt of the Ionian cities took place. It was suppressed, at first, but the Atticans, at Marathon, defeated the Persian warriors, B.C. 490, and the great victory changed the whole course of Asiatic conquest. Darius made vast preparations for a new invasion of Greece, but died before they were completed, after a reign of thirty-six years, B.C. 485, leaving a name greater than that of any Oriental sovereign, except Cyrus. (M198) Unfortunately for him and his dynasty, he challenged the spirit of western liberty, then at its height among the cities of Greece. His successor, Xerxes, inherited his power, but not his genius, and rashly provoked Europe by new invasions, while he lived ingloriously in his seraglio. He was murdered in his palace, the fate of the great tyrants of eastern monarchies, for in no other way than by the assassin’s dagger could a change of administration take place—a poor remedy, perhaps, but not worse than the disease itself. This tyrant was the Ahasuerus of the Scriptures. (M199) We need not follow the fortunes of the imbecile princes who succeeded Xerxes, for the Persian monarchy was now degenerate and weakened, and easily fell under the dominion of Alexander, who finally overthrew the power of Persia, B.C. 330.
