THE PERSIAN EMPIRE.
i. Political History.
Kinship of the Medes and Persians.—It was in very remote times, that some Aryan tribes, separating themselves from the other members of the Aryan family, sought new abodes on the plateau of Iran. The tribes that settled in the south became known as the Persians; while those that took possession of the mountain regions of the northwest were called Medes. The Medes, through mingling with native non-Aryan tribes, became quite different from the Persians; but notwithstanding this, the names of the two peoples were always very closely associated, as in the familiar legend, "The law of the Medes and Persians, which altereth not."
The Medes at first the Leading Race.—Although the Persians were destined to become the dominant tribe of all the Iranian Aryans, still the Medes were at first the leading people. Cyaxares (625–585 B.C.) was their first prominent leader and king. We have already seen how, aided by the Babylonians, he overthrew the last king of Nineveh, and burned that capital (see p. 51). Cyaxares was followed by his son Astyages (585–558 B.C.), during whose reign the Persians, whom Cyaxares had brought into at least partial subjection to the Median crown, revolted, overthrew the Median power, and thenceforth held the place of leadership and authority.
