The dismissal of Polydamas implied a mortifying confession of weakness on the part of Sparta. It marks, too, an important stage in the real decline of her power. Eight years before, at the instance of the Akanthian envoys, backed by the Macedonian Amyntas, she had sent three powerful armies in succession to crush the liberal and promising confederacy of Olynthus, and to re-transfer the Grecian cities on the sea-coast to the Macedonian crown. The region to which her armies had been sent, was the extreme verge of Hellas. The parties in whose favor she acted, had scarcely the shadow of a claim, as friends or allies; while those _against_ whom she acted, had neither done nor threatened any wrong to her: moreover, the main ground on which her interference was invoked, was to hinder the free and equal confederation of Grecian cities. _Now_, a claim, and a strong claim, is made upon her by Polydamas of Pharsalus, an old friend and ally. It comes from a region much less distant; lastly, her political interest would naturally bid her arrest the menacing increase of an aggressive power already so formidable as that of Jason. Yet so seriously has the position of Sparta altered in the last eight years (382-374 B.C.), that she is now compelled to decline a demand which justice, sympathy, and political policy alike prompted her to grant. So unfortunate was it for the Olynthian confederacy, that their honorable and well-combined aspirations fell exactly during those few years in which Sparta was at her maximum of power! So unfortunate was such coincidence of time, not only for Olynthus, but for Greece generally:—since nothing but Spartan interference restored the Macedonian kings to the sea-coast, while the Olynthian confederacy, had it been allowed to expand, might probably have confined them to the interior, and averted the death-blow which came upon Grecian freedom in the next generation from their hands.
