The political condition of Persia under these early monarchs is a more interesting question than either the names of the kings or the foreign alliances which they attracted. According to Herodotus, that condition was one of absolute and unqualified subjection to the sway of the Medes, who conquered Persia and imposed their yoke upon the people before the year B.C. 634. The native records, however, and the accounts which Xenophon preferred, represent Persia as being at this time a separate and powerful state, either wholly independent of Media, or, at any rate, held in light bonds of little more than nominal dependence. On the whole, it appears most probable that the true condition of the country was that which this last phrase expresses. It maybe doubted whether there had ever been a conquest; but the weaker and less developed of the two kindred states owned the suzerainty of the stronger, and though quite unshackled in her internal administration, and perhaps not very much interfered with in her relations towards foreign countries, was, formally, a sort of Median fief, standing nearly in the position in which Egypt now stands to Turkey. The position was irksome to the sovereigns rather than unpleasant to the people. It detracted from the dignity of the Persian monarchs, and injured their self-respect; it probably caused them occasional inconvenience, since from time to time they would have to pay their court to their suzerain; and it seems towards the close of the Median period to have involved an obligation which must have been felt, if not as degrading, at any rate as very disagreeable. The monarch appears to have been required to send his eldest son as a sort of hostage to the Court of his superior, where he was held in a species of honorable captivity, not being allowed to quit the Court and return home without leave, but being otherwise well treated. The fidelity of the father was probably supposed to be in this way secured while it might be hoped that the son would be conciliated, and made an attached and willing dependent.
