After the battle of Leuctra, the Eleans had again taken possession of the territory of Triphylia, which had once been wrested from them by the Spartans; but the inhabitants, dissatisfied with the rule of the Eleans, had turned to the Arcadians, and, appealing to the ancient connection between the races, had requested and obtained admission into the Arcadian confederacy. The suzerainty of Elis over Triphylia had indeed, as it seems, been recognised in the peace prescribed by Persia, but the latter’s dispositions received as little acceptance here as elsewhere; both sides were therefore prepared to vindicate their claims by force of arms. [Sidenote: [365-364 B.C.]] To strengthen their position the Eleans concluded an alliance with Sparta, and vacated the border town of Lasion on the western slope of Erymanthus in favour of a flock of oligarchical refugees from Arcadia. In this settlement the government of Megalopolis saw a hostile intention, for from thence the oligarchs had no difficulty in forming traitorous connections with those who thought with them, and they seized the occasion to visit the peaceful little country with a devastating war. They carried robbery and destruction up to the very capital, excited a sanguinary civil war between the popular party and the oligarchical families, and reduced the inhabitants to a state of despair. In vain the Eleans brought about an invasion of the friendly Spartans into the territory of Megalopolis; after an heroic struggle the Arcadians forced the Lacedæmonian king, Archidamus, to surrender the strong hill town of Cromnus, which he had occupied by a rapid movement, and forced him to a disastrous retreat during which a hundred Lacedæmonian citizens fell into the hands of the victors. And as it chanced that the time of the Olympic games was approaching, they took possession of the holy site and bestowed the office of judge of the contests on the Pisatans.
