When Byzantine princess Maria Palaiologina left for Mongolia for her arranged marriage to Mongolian monarchy, it was a common imperial diplomatic move that wrote a unique chapter in Byzantine history and Christian Orthodoxy
The history of the Byzantine Empire in the 13th century was shaped not only by military conflicts and religious controversies but also by diplomacy, dynastic marriages, and cultural exchange. The marriage of Maria Palaiologina, daughter of the Byzantine emperor Michael VIII Palaiologos, to Mongol ruler Abaqa Khan is a perfect example of imperial diplomacy. It would forge good relations with the Mongols, a guarantee that they would not attack Constantinople.
Maria was an illegitimate daughter of Michael VIII Palaiologos, the emperor who restored Byzantine rule in Constantinople in 1261 after the Latin occupation (1204-1261). Her marriage was part of Michael’s wider diplomatic policy. In 1265 she was sent eastward with the intention of marrying Hülegü Khan, grandson of Genghis Khan and founder of the Ilkhanate – a Mongol khanate founded in the southwestern territories of the Mongol Empire – and ruler of Persia.
However, Hülegü Khan died before Maria reached the Mongol court, and she subsequently married his son Abaqa Khan. She remained in the Ilkhanate for approximately fifteen to seventeen years. Recent scholarship emphasizes the diplomatic significance of this marriage, describing Maria as a princess situated “between two worlds,” Byzantine and Mongol. Scholar Ignacio Blas Alonso argues that Michael VIII Palaiologos used his daughters as instruments of diplomacy, sending Maria to the newly established Ilkhanate in order to strengthen political relations between Constantinople and the Mongol rulers.
An unexpected change
However, Hülegü Khan died before Maria reached the Mongol court, and she subsequently married his son, Abaqa Khan. She remained in the Ilkhanate for approximately fifteen to seventeen years. Recent scholarship emphasizes the diplomatic significance of this marriage, describing Maria as a princess situated “between two worlds,” Byzantine and Mongol.
The marriage should therefore not be interpreted simply as a personal union. It represented the political needs of a weakened Byzantine Empire. Michael VIII was attempting to protect Constantinople from powerful enemies, particularly the Mamluks and the Latin powers of the West. Alexander van Millingen, an important historian of Constantinople’s Byzantine churches, described Maria’s marriage as having been prompted by “no romantic sentiment,” but as part of a wider policy of matrimonial alliances designed to secure Byzantine interests. His observation captures the essentially political nature of Maria’s journey to the Mongol court.
Maria’s position in the Ilkhanate was nevertheless more complicated than that of a passive diplomatic bride. She remained a committed Christian, while Abaqa himself did not convert to Christianity. Modern scholarship stresses that Abaqa’s attitude toward Christianity was politically useful but should not be confused with complete religious commitment. The Encyclopaedia Iranica, for example, warns that Abaqa’s Christian sympathies “should not be exaggerated,” noting that he continued to maintain traditional Mongol religious beliefs and also showed interest in Buddhism. Maria therefore lived within a religiously plural environment in which Christianity, Buddhism, Islam, and indigenous Mongol traditions existed alongside one another.
The Byzantine princess becomes ‘Lady of the Mongols’
The Byzantine princess became known in the Mongol world as Despina Khatun, or the “Lady of the Mongols.” Maria developed an independent religious identity inside the world of the Mongols. Her Christian identity appears to have remained central throughout her years in Persia. Recent Byzantine scholarship records that during her approximately seventeen years in the Ilkhanate, Maria remained Christian and was associated with the foundation of an Orthodox church in Tabriz. Her religious role consequently extended beyond her personal faith. She became associated with Christian communities living within the Mongol territories and acquired a reputation that survived long after her return to Constantinople.
The death of Abaqa in 1282 marked a decisive turning point in Maria’s life. She eventually returned to Constantinople and devoted herself increasingly to religious life. It was during this period that she became associated with the monastery and church later known as Saint Mary of the Mongols. The popular name of the church, Panagia Mouchliotissa, literally associates the Virgin Mary with the Mongols and preserves the memory of Maria’s extraordinary experience in Persia.
Return to Constantinople and her church
There are some disputes in regards to the Panagia Mouchliotissa church. Older accounts sometimes presented Maria as the founder or builder of the existing structure. Archaeological and architectural scholarship has modified this interpretation. The Byzantine architectural historian Charalambos Bouras demonstrated that the church was considerably older than the Palaiologan period and was not originally erected in 1266–1267, as had sometimes been claimed. Instead, the building belonged to an older monastery known as the Panaghia or Panagiotissa. Maria acquired the church and associated buildings around 1282. Thus, her importance lies particularly in her role as patron, restorer, and ktētorissa rather than necessarily founder of the physical building.
This distinction is crucial for understanding the significance of Saint Mary of the Mongols. Maria transformed an older Byzantine religious institution into a monument connected with her extraordinary diplomatic and religious career. The name “of the Mongols” was attached to the church because of Maria’s marriage and her long association with the Mongol court. In this sense, the church became a material representation of the encounter between Byzantium and the Mongol world.
The concept of the ktētor (κτήτωρ in Greek)was particularly important in Byzantine religious culture. A ktētor was a patron or founder who provided financial or material support for a church or monastery and thereby established a lasting spiritual relationship with the institution. Maria’s association with the church allowed her to transform her personal history into a permanent religious legacy. Her experience as a Mongol princess was therefore not erased when she returned to Constantinople; instead, it became incorporated into the religious landscape of the Byzantine capital.
The Byzantine church
The church’s continued existence is itself remarkable. It is one of the surviving Byzantine churches of Istanbul and has remained associated with the Greek Orthodox community. Its historical identity has been inseparable from Maria Palaiologina’s story. A modern scholarly study by Ilyas Kemaloğlu emphasizes that the church is particularly significant because of both “its story of foundation and its name,” linking it directly to Byzantine-Mongol relations.
Modern architectural research has shown that Maria did not necessarily construct the church from its foundations; rather, she acquired and restored an older institution and became its celebrated ktētorissa. Her legacy therefore lies not simply in architecture but in the way she connected Byzantine dynastic politics, Mongol diplomacy, Christianity, and female patronage.
The church is called by the Turks “Kanlı Kilise” (the Bloodstained Church), as the building saw violent combat during the capture of Constantinople by the Ottomans in 1453. The church is the only one in Constantinople to have never been converted to a mosque, following an order by Mehmet the Conqueror. It is the only surviving Byzantine church of Constantinople that has always remained a functioning house of worship of the Greek Orthodox Church. It is located in Tevkii Cafer Mektebi Lane, in the quarter of Fener.
Maria Palailogina Legacy
Maria Palaiologina’s religious identity is also reflected in the art of the Chora Monastery. The church of the monastery was officially dedicated to the Virgin Mary. It is known for its Byzantine frescoes and hagiography.
Scholars have identified the nun Melania represented in the Deesis mosaic of the inner narthex with Maria Palaiologina, although the identification has been the subject of scholarly discussion. Scholar Natalia Teteriatnikov’s study of the image examines precisely “the place of the nun Melania” within the Deesis program and the significance of her unusually prominent position. The inscription identifies the woman as a member of the Palaiologan dynasty and as the “Lady of the Mongols.”
Scholar Natalia Teteriatnikov’s study of the image examines precisely “the place of the nun Melania” within the Deesis program and the significance of her unusually prominent position. This visual representation is important because it shows Maria not primarily as a political bride but as a Byzantine woman who ultimately entered religious life.
