42. The insurrection and rout of Cyrus produced a corresponding change in the political relations between the Persian court and Sparta: which, however, were now determined, not so much by the will of the monarch himself, as by the satraps of Asia Minor, Tissaphernes and Pharnabazus, of whose jealousy Sparta knew how to take advantage. The former, by his severity towards the Asiatic Greeks, who had supported the cause of Cyrus, excited a war with Sparta, in which he himself fell a victim. The death of the satrap is not, however, succeeded by tranquillity; for Agesilaus commands in Asia, and threatens to overthrow the Persian throne itself. The policy of the Persians is shown by the war which they foment in Greece against Sparta: Conon is placed at the head of their fleet, and extricates Persia from her difficulties better than could have been done by her own generals; in the peace of Antalcidas she herself dictates the terms, by which the Grecian colonies of Asia Minor, together with Cyprus and Clazomenae, are again delivered into her possession. The rising power of Thebes under Epaminondas and Pelopidas, with whom Persia keeps up a friendly connection, ensures her from any future blow at the hands of the Spartans.--War for the possession of Cyprus with Evagoras, who, however, by the subsequent peace retains the sovereignty of Salamis. 43. The war against the Cadusii in the mountains of Caucasus, proves that Artaxerxes II. was not fitted for military command; and his attempt to recover Egypt from king Nectanebus I. which was defeated by the feud between Iphicrates and Artabazus, evinces that the most numerous Persian host could achieve nothing without the assistance of Grecian troops and Grecian generals.--It could hardly be expected that an empire should endure much longer, when in the court all was ruled by the desire of revenge in the women; when the political organization was already so corrupt, that the satraps waged war against each other; and when those generals who gave any proof of talent received no better reward than that of Datames. 44. In fact, it seemed not unlikely that the Persian empire would fall asunder a little before the death of Artaxerxes Mnemon. A quarrel about the succession arose in the court between the three legitimate sons of the king, the eldest of whom, Darius, was put to death: the standard of rebellion was erected in the western half of the empire, and joined by all the governors of Asia Minor and Syria, supported by Tachos, king of Egypt, to whose assistance the Spartans had sent Agesilaus. The insurrection, however, was quelled in consequence of the treachery of the chief leader, Orontes, who was bribed over to the court.
