George, Emperor of Trebizond

George Megas Komnenos (Greek: Γεώργιος Μέγας Κομνηνός, Geōrgios Mégas Komnēnos; c. 1255 – after 1284) was Emperor of Trebizond from 1266 to 1280. He was the elder son of Emperor Manuel I and his third wife, Irene Syrikaina, a Trapezuntine noblewoman. He succeeded his half-brother Andronikos in 1266 and ruled for 14 years. George was the first Trapezuntine emperor to officially use the style Megas Komnenos ("grand Komnenos"), which had previously been merely a nickname.
