Alexios IV Megas Komnenos or Alexius IV
(Greek: Αλέξιος Δ΄ Μέγας Κομνηνός, Alexios IV Megas Komnēnos), (1382–1429), Emperor of Trebizond from March 5, 1417 to October 1429. He was the son of Emperor Manuel III and Gulkhan-Eudokia of Georgia.
Alexios IV had been associated in authority and given the title of despotes by his father as early as 1395. Nevertheless, the two quarreled as Alexios was impatient to assume supreme power; William Miller compared this to “the first three sovereigns of the House of Hanover” for whom “the heir-apparent always quarrelled with his father.” When his father died in 1417, Alexios was accused by some of having expedited his death. Alexios inherited a conflict with the Genoese, who defeated the fleet of Trebizond and seized a local monastery, which they converted into a fortress. By 1418 he had signed a peace agreement and paid reparations to the Genoese until 1422. A new dispute arose over the emperor’s obligations in 1425 and was not resolved until 1428. Relations with the Republic of Venice were generally better.
