In 435 B.C. the Greek city of Epidamnus, a colony of Corcyra suffering internal unrest and external hostilities, appealed for military assistance from its mother country. It was rebuffed. It took its case to Corinth; and the Corinthians, motivated in part by hatred of Corcyra, which was in turn a colony of Corinth, agreed to come to the assistance of Epidamnus. The Corcyreans reacted violently to this action, and hostilities commenced between Corinth and Corcyra.
