John I of Trebizond

John I Komnenos Axouch (Greek: Ιωάννης Κομνηνός Ἀξούχος, romanized: Iōannēs Komnēnos Axouch) was the Emperor of Trebizond from 1235 to 1238. One editor reads the text of the chronicle of Michael Panaretos as stating that John ruled six years; although William Miller follows Fallmerayer in assuming this was a mistake for three years, another possible solution is that John was co-ruler with his predecessor Andronikos I Gidos for three years then ruled alone for three more.
