The Battle of Pelekanon, also known by its Latinised form Battle of Pelecanum, occurred on June 10–11, 1329, between an expeditionary force by the Byzantines led by Andronikos IIl and an Ottoman army led by Orhan I. The Byzantine army was defeated, with no further attempt made at relieving the cities in Anatolia under Ottoman siege.

Significance

The Battle of Pelekanon was fought between a Byzantine expeditionary force under Andronikos III Palaiologos and John Kantakouzenos and an Ottoman army under Orhan Ghazi, with the Byzantines committing approximately 4,000 troops against an Ottoman force roughly twice that size. The Byzantine army was defeated, and the engagement carried immediate strategic consequences: no further attempt was made to relieve the Byzantine cities in Anatolia that were under Ottoman siege. The battle thus effectively ended Byzantine efforts to contest Ottoman expansion in the region, leaving those besieged cities without hope of imperial rescue and accelerating the Ottoman consolidation of Anatolian territory during the broader Byzantine–Ottoman wars.
