Cyaxares had rescued Media from the most extreme peril. The consequences of the defeat, in which his father, with the greatest part of his army, fell before the Assyrians, had been averted. Though subsequently overpowered by the Scythians, he yet became once more sovereign in his own country. This rise of Media, and the weakening of the Assyrian kingdom by the inundation of the Scythians, he used in order to subjugate Armenia and Cappadocia. And though he was not able to achieve anything decisive against the Lydians, he attained a greater success; in combination with Babylonia he avenged on the Assyrians the supremacy they had exercised over Media; he overthrew the remnant of that kingdom, whose tough vigour showed itself even at the final hour in an obstinate resistance. It was a great achievement and at the same time an important extension of the Median dominions, not merely by the whole extent of the Assyrian country on the left bank of the Tigris, which fell to Media, but also by the closer connection which Cyaxares thus obtained with Armenia and Cappadocia, the subject lands to the west. Then followed the spread of the Median power over the kindred nations in the north and east of Iran. The Persians were already subjected to Phraortes, and Cyaxares brought under his sovereignty the Sagartians, Hyrcanians, Parthians, and Bactrians; he made the Sacæ dependant on him, and in the east perhaps extended his power as far as the Indus. From his proud citadel at Ecbatana he ruled from the Halys to the Oxus. It was a powerful empire. Herodotus depicts the reign of Cyaxares when he says: "He was far more powerful than his predecessors." With the Medes he passes as the founder of their sovereignty; and his reign must have been held in grateful remembrance, not by the Medes only, but also by the subject nations. Those who afterwards attempted to bring the Medes and Sagartians under arms against the dominion of the Persians, called themselves the descendants of Cyaxares--and one even laid aside his own name, Phraortes, to do so.
