Franco-Mongol Alliance

Franco-Mongol Alliance

Franco-Mongol relations were established in the 13th century, as Christian Crusaders and the Mongol Empire attempted to form a Franco-Mongol alliance against the Muslims. Such an alliance might have seemed an obvious choice: the Mongols were already sympathetic to Christianity, given the presence of many influential Nestorian Christians in the Mongol court. The Franks (Western Europeans and those in the Crusader States of the Levant) were open to the idea of support from the East, owing to the long-running legend of the mythical Prester John, an Eastern king in a magical kingdom whom many believed would one day come to the assistance of the Crusaders in the Holy Land. The Franks and Mongols also shared a common enemy in the Muslims, but despite many messages, gifts, and emissaries over the course of several decades, the often-proposed alliance never came to fruition.

Contact between Europeans and Mongols began around 1220, with occasional messages from the papacy and European monarchs to Mongol leaders such as the Great Khan, and subsequently to the Ilkhans in Mongol-conquered Iran. Communications tended to follow a recurring pattern: the Europeans asked the Mongols to convert to Western Christianity, while the Mongols responded with demands for submission and tribute. The Mongols had already conquered many Christian and Muslim nations in their advance across Asia, and after destroying the Muslim Abbasid and Ayyubid dynasties, for the next few generations fought the remaining Islamic power in the region, the Egyptian Mamluks. Hethum I, king of the Christian nation of Cilician Armenia, had submitted to the Mongols in 1247, and strongly encouraged other monarchs to engage in a Christian-Mongol alliance, but was only able to persuade his son-in-law, Prince Bohemond VI of the Crusader State of Antioch, who submitted in 1260. Other Christian leaders such as the Crusaders of Acre were more mistrustful of the Mongols, perceiving them as the most significant threat in the region. The Barons of Acre therefore engaged in an unusual passive alliance with the Muslim Mamluks, allowing Egyptian forces to advance unopposed through Crusader territory to engage and defeat the Mongols at 1260's pivotal Battle of Ain Jalut.

European attitudes began to change in the mid-1260s, from perceiving the Mongols as enemies to be feared, to potential allies against the Muslims. The Mongols sought to capitalize on this, promising a re-conquered Jerusalem to the Europeans in return for cooperation. Attempts to cement an alliance continued through negotiations with many leaders of the Mongol Ilkhanate in Iran, from its founder Hulagu through his descendants Abaqa, Arghun, Ghazan, and Öljaitü, but without success. The Mongols invaded Syria several times between 1281 and 1312, sometimes in attempts at joint operations with the Franks, but the considerable logistical difficulties involved meant that forces would arrive months apart, never able to coordinate activities in any meaningful way. The Mongol Empire eventually dissolved into civil war, and the Egyptian Mamluks successfully recaptured all of Palestine and Syria from the Crusaders. After the Fall of Acre in 1291, the remaining Crusaders retreated to the island of Cyprus. They made a final attempt to establish a bridgehead at the small island of Ruad off the coast of Tortosa, again in an attempt to coordinate military action with the Mongols, but the plan failed, and the Muslims responded by besieging the island. With the Fall of Ruad in 1302 or 1303, the Crusaders lost their last foothold in the Holy Land.

Modern historians debate whether an alliance between the Franks and Mongols would have been successful in shifting the balance of power in the region, and if it would have been a wise choice on the part of the Europeans. Traditionally, the Mongols tended to see outside parties as either subjects or enemies, with little room in the middle for a concept such as an ally.
