Alexios II Megas Komnenos

Alexios II Megas Komnenos (1282–1330), elder son of John II and Eudokia Palaiologina, became emperor of Trebizond in 1297 at fourteen, ruling at the empire's peak. Around 1300 he married Jiajak Jaqeli, daughter of the atabeg of Samtskhe, without the consent of his guardian and uncle Andronikos II.

In 1301–1302 he routed Turkoman raiders who had sacked Kerasous and captured their general. He later checked the Genoese by treaties and granted Venice equal privileges.

After Sinopite pirates burned Trebizond, he built the harbour sea walls in 1324. He died of plague on 3 May 1330, succeeded by Andronikos III.
