After the fall of Assyria the leading portion passed to Media, Babylonia, and Lydia. As the two first had united for the overthrow of Assyria, and had come to terms with Lydia for this object, so in other respects they displayed a friendly feeling towards each other. The daughter of Cyaxares became the consort of Nebuchadnezzar of Babylon, and the daughter of Alyattes, king of Lydia, was married to his son Astyages. Afterwards, Babylon prevented the attempt of Egypt to unite Syria with the land of the Nile; it was eagerly occupied with subjugating Mesopotamia and Syria, while Lydia established its power over the tribes and cities of Asia Minor as far as the Halys. Neither Media nor Lydia thought of putting any hindrances in the way of the extension of the Babylonian dominion over Syria and Phoenicia. Of these three kingdoms, thus connected by mutual alliances, Media was the strongest. Babylonia and Lydia were not equal either in extent of country or amount of population; Lydia was perhaps inferior in the vigour of the ruling tribe, and Babylonia certainly inferior in the military strength of the population. Even when united they did not reach the size or strength of the Median power, whose army Cyaxares had arranged, and for which he had provided at Ecbatana a strongly fortified centre, equidistant from the Halys and the Oxus. When Astyages ascended the throne, on the death of his father in 593 B.C., he entered upon the inheritance of a secure dominion in peaceful and friendly relations to all the neighbouring powers. While his father-in-law, Alyattes of Lydia, and his son Croesus were occupied in subjugating the Carians and the Greek cities on the west coast of Anatolia (III. 439), and Nebuchadnezzar carried on one campaign after another in order to incorporate in his kingdom the great trading marts of the Syrian coasts, Astyages could enjoy, for more than thirty years, the fruits of the efforts by which his father had founded and established the Median empire.

In Xenophon, who represents Astyages as reigning before Cyaxares, Astyages had subjugated the king of Armenia; the rebellion of this king was afterwards repressed by Cyaxares.
