One daughter, was married to Kara Yusuf's son Jihan Shah in c.1420, and Alexios agreed to pay his son-in-law the same amount of tribute that had previously been due to Tamerlane.
Alexios' marital policy also extended to his Christian neighbours, and his eldest daughter was married to Serbian nobleman, later despot, Djuradj Branković.
[5] According to George Finlay, Alexios IV spent much of his time in pursuit of pleasure and accomplished relatively little,[8] although there is no evidence in contemporary sources for this claim.
[9] When Alexios IV's wife Theodora died in 1426, he was so distraught that Bessarion wrote him no less than three monodias, which help to shed some light on this otherwise dark period lacking in sources.
[10] Alexander fled Trebizond; the Venetian traveller Pero Tafur encountered him in Constantinople around October of that year, living with his sister Maria.
During the 1923 Exchange of Populations, Chaldian antiquary George Kandilaptes collected as much of these bones as he could and brought them to Greece, where they were stored in the Byzantine and Christian Museum in Athens.
Then in 1980 the remains of Alexios IV Megas Komnenos were brought with much ceremony to a final resting place in New Soumela, near Kastania in Imathia.
