Megabyzus, the satrap of that important province, offended at the execution of Inarus, in violation of the promise which he had himself made to him, raised a revolt against his sovereign, defeated repeatedly the armies sent to reduce him to obedience, and finally treated with Artaxerxes as to the terms on which he would consent to be reconciled.

Thus was set an example, if not of successful insurrection, yet at any rate of the possibility of rebelling with impunity--an example which could not fail to have a mischievous effect on the future relations of the monarch with his satraps.

It would have been better for the Empire had Megabyzus suffered the fate of Oroetes, instead of living to a good old age in high favor with the monarch whose power he had weakened and defied.
Artaxerxes survived the "Peace of Callias" twenty-four years.

His relations with the Greeks continued friendly till his demise, though, on the occasion of the revolt of Samos (B.C.

440), Pissuthnes, satrap of Sardis, seems to have transgressed the terms of the treaty, and to have nearly brought about a renewal of hostilities.
