Maria Palaiologina

[ Her father arranged her marriage to Hulagu Il-Khan, but by the time she arrived at his court he had died and she was married to his son instead. Vardan's History records that "Abaqa was brought a wife from the Byzantines named Despina, daughter of the king called Vatatzes" in [14 Jan 1265/13 Jan 1266] and that he was baptised at her request[331]. She was known as Despina Khatun at the Il-Khan court[332]. She founded the convent of Mugulion after 1281. She [married secondly ([1307/08]%29 Charbanden, Turkish prince]. Pachymeres records that Emperor Andronikos II negotiated an alliance with "Charmpantane" and proposed his marriage to "sororem propriam Mariam…dominæ Mugullorum", granting her "comitatu deduci Nicæam" which had been invaded by the Persians, dated to [1307/08] from the context[333]. It is not clear from the text whether this marriage ever took place, especially as it is unclear why Charbanden would have considered Maria a good marriage prospect as she must have been in her 50s or early 60s at the time, assuming that the date of her first marriage is correct. ] ref http://fmg.ac/Projects/MedLands/MONGOLS.htm#NairaquBuqa

After Abaqa's death, his widow Maria fled back to Constantinople where her father, apparently wishing to spare his capital the fate that befell Baghdad, tried to marry her off again to another Mongol khan. Maria could not accept the offer, became a nun, and founded the church of Panagia Mouchliotissa around 1285.
