Peloponnesian War and later In the war, Elis sided at first with Sparta. But Sparta, jealous of the increasing prosperity of its ally, availed itself of the first pretext to pick a quarrel. At the Battle of Mantinea (418 BC), the Eleans fought against the Spartans, who later took vengeance upon them by depriving them of Triphylia and the towns of the Acroreia. The Eleans made no attempt to re-establish their authority over these places until Thebes rose in importance after the Battle of Leuctra (371 BC). However, the Arcadian confederacy came to the assistance of the Triphylians. In 366 BC, hostilities broke out between them, and though the Eleans were at first successful, they were soon overpowered; their capital very nearly fell into the hands of the enemy, and the territory of Triphylia was permanently ceded to Arcadia in 369 BC.Oxford Classical Dictionary, third edition.
