Surnamed Mnemon (Μνήμων) from his good memory, succeeded his father, Dareius II., as king of Persia, and reigned from B. C. 405 to B. C. 362. (Diod. 13.104, 108.) Cyrus, the younger brother of Artaxerxes, was the favourite of his mother Parysatis, and she endeavoured to obtain the throne for him; but Dareius gave to Cyrus only the satrapy of western Asia, and Artaxerxes on his accession confirmed his brother in his satrapy, on the request of Parysatis, although he suspected him. (Xenoph. Anab. 1.1.3 ; Plut. Art. 3.) Cyrus, however, revolted against his brother, and supported by Greek mercenaries invaded Upper Asia. In the neighbourhood of Cunaxa, Cyrus gained a great victory over the far more numerous army of his brother, B. C. 400], but was slain in the battle. [CYRUS.] Tissaphernes was appointed satrap of western Asia in the place of Cyrus (Xenoph. Hellen. 3.1.3), and was actively engaged in wars with the Greeks. [THIMBRON; DERCYLLIDAS; AGESILAUS.]
Notwithstanding these perpetual conflicts with the Greeks, the Persian empire maintained itself by the disunion among the Greeks themselves, which was fomented and kept up by Persian money. The peace of Antalcidas, in B. C. 388, gave the Persians even greater power and influence than they had possessed before. [ANTALCIDAS.] But the empire was suffering from internal disturbances and confusion : Artaxerxes himself was a weak man; his mother, Parysatis, carried on her horrors at the court with truly oriental cruelty; and slaves and eunuchs wielded the reins of government. Tributary countries and satraps endeavoured, under such circumstances, to make themselves independent, and the exertions which it was necessary to make against the rebels exhausted the strength of the empire. Artaxerxes thus had to maintain a long struggle against Evagoras of Cyprus, from B. C. 385 to B. C. 376, and yet all he could gain was to confine Evagoras to his original possession, the town of Salamis and its vicinity, and to compel him to pay a moderate tribute. (Diod. 15.9.) At the same time he had to carry on war against the Cardusians, on the
