Jiajak Jaqeli (Georgian: ჯიაჯაყ ჯაყელი) (sometimes given as Djiadjak) was the Empress consort of Alexios II of Trebizond.
[citation needed] The Jaqelis held the Georgian feudal office of Eristavi, which could be "governor of a region" or an "army-commander",[1] roughly equivalent to the Byzantine strategos and normally translated into English as "duke".
[citation needed] The Byzantine Emperor Andronikos II Palaiologos had been his guardian and wanted Alexios to marry a daughter of the high court official Nikephoros Choumnos, but, without asking for the permission, the young man instead married jiajak Jaqeli.
Andronikos appealed to the Church to annul the marriage but the Patriarch refused to assist him, on the ground that Jiajak was reported to be already pregnant.
Alexios' mother Eudokia Palaiologina, who returned to Trebizond on the pretext of inducing her son to dissolve the marriage, advised him to keep his Iberian wife.
