George Megas Komnenos

George Megas Komnenos (c. 1255 – after 1284), elder son of Manuel I and Irene Syrikaina, succeeded his half-brother Andronikos as emperor of Trebizond in 1266 and ruled fourteen years. A boy at his accession, he first ruled through a regent and was the first Trapezuntine emperor styled Megas Komnenos.

After Michael VIII Palaiologos accepted church union at Lyons in 1274, anti-unionist refugees cast George as Orthodoxy's champion and pressed him to seek the throne of Constantinople. In June 1280 his officials betrayed him and captured him. In 1284 he failed to seize Trebizond from his brother John II, then vanished from the sources.
