Michael Megas Komnenos
Michael Megas Komnenos (c. 1288–after 1355) was a younger son of Emperor John II of Trebizond and Eudokia. Raised in Constantinople, he married Acropolitissa and fathered John III. In 1341 he claimed Trebizond's throne but nobles imprisoned him.
Freed by Niketas Scholares, he was crowned emperor in 1344, deposed his son John III, and reigned until he was toppled in 1349. Forced into a monastery and exiled to Constantinople, he was released in 1355, failed to regain it and died soon after.
