But such help as she needed was not wanting to her. The rapid strides with which Media had advanced towards the west had no doubt alarmed the numerous princes of Asia Minor, who must have felt that they had a power to deal with as full of schemes of conquest as Assyria, and more capable of carrying her designs into execution. It has been already observed that the long course of Assyrian aggressions developed gradually among the Asiatic tribes a tendency to unite in leagues for purposes of resistance. The circumstances of the time called now imperatively for such a league to be formed, unless the princes of Asia Minor were content to have their several territories absorbed one after another into the growing Median Empire. These princes appear to have seen their danger. Cyaxares may perhaps have, declared war specially against the Lydians, and have crossed the Halys professedly in order to chastise them; but he could only reach Lydia through the territories of other nations, which he was evidently intending to conquer on his way; and it was thus apparent that he was activated, not by anger against a particular power, but by a general design of extending his dominions in this direction. A league seems therefore to have been determined on. We have not indeed any positive evidence of its existence till the close of the war; but the probabilities are wholly in favor of its having taken effect from the first. Prudence would have dictated such a course; and it seems almost implied in the fact that a successful resistance was made to the Median attack from the very commencement. We may conclude therefore that the princes of Asia Minor, having either met in conclave or communicated by embassies, resolved to make common cause, if the Medes crossed the Halys; and that, having already acted under Lydia in the expulsion of the Cimmerians from their territories, they naturally placed her at their head when they coalesced for the second time.
