The Mongols were famous for their ultimatums of destruction and submission. No shortage of thirteenth century states received demands for their unconditional surrender to the Great Khan granted divine mandate to rule by Eternal Blue Heaven. Initially, the Mongol imperial ideology was extremely black and white: you could submit to Mongol rule, or face total annihilation. There was no room for other relationships, for the Great Khan had no allies, only subjects. But as the thirteenth century went on and the dream of Chinggisid world hegemony slipped away as the divisions of the Mongol Empire went their separate ways, the Mongol Khans in the west began to seek not the capitulation, but the cooperation of western Europe to aid in their wars against Mamluks. For the Ilkhanate’s sixty-year struggle against the Mamluk Sultanate, the Il-Khans sought to bring the Popes and Monarchs of Europe to a new crusade to assist in the defeat of the Mamluks, an ultimately fruitless endeavour, and the topic of today’s episode. I’m your host David, and this is Kings and Generals: Ages of Conquest.       The first Mongol messages to the Kings of Europe came in the late 1230s and 40s, accompanying Batu and Sube’edei’s western invasion, asking the Hungarians how they possibly could hope to flee the grasp of the Mongols. We know the Mongols sent a number of envoys to European monarchs and dukes, and employed a variety of peoples in this enterprise, including at least one Englishman. Over the 1240s and 50s, European envoys like John de Plano Carpini or William of Rubrucks to the Mongol Empire returned from Karakorum with orders for the Kings and Popes to come to Mongolia and submit in person.While Rus’ and Armenian lords and kings did do so, there is little indication that European rulers even responded to these demands. For the Mongols, who seemed poised to dominate everything under the Eternal Blue Sky, there was little reason to adopt more conciliatory language. From their point of view, the Europeans were only stalling the inevitable: soon Mongol hoofbeats would certainly be heard in Paris and Rome. The Mongols treated the European states as their diplomatic inferiors, subjects basically in a state of rebellion by fact that they had not already submitted. Cruel, threatening and demanding letters were the norm, and it’s safe to say any future efforts at alliance were greatly hampered by this opening salvo. The rare diplomatic exception was an embassy sent to King Louis IX of France during his stay in Cyprus in 1248 just before the 7th Crusade. There, messengers came from the Mongol commander in the west, Eljigidei, an ally to the reigning Great Khan, Guyuk. Headed by two Christians in Eljigidei’s service, the embassy bore letters from Eljigidei. These letters called Louis ‘son,’ and had no demand of submission, but mentioned Mongol favouritism to Christians, urged the French King not to discriminate between Latin and non-Latin Christians as all were equal under Mongol law, and wished him well in his crusade. The two Christian representatives of Eljigidei asserted that he was a Christian and that Guyuk himself had already been baptised. The urged Louis to attack Egypt, and prevent its Ayyubid prince from sending forces to aid the Caliph in Baghdad, who the Mongols were soon to attack.     Louis, is should be noted, almost certainly had not been anticipating any cooperation from the Mongols; he had  been well aware of their attacks on Hungary only a few years before, learned of Mongol demands and treatment of foreign powers from travellers like Carpini, and apparently received Mongol ultimatums for his submission in 1247. Further, a devout Christian, it is unlikely he would have gone looking for allies among “pagans,” even for fighting against Muslims. Still, he reacted well to Eljigidei’s messengers and sent a return embassy with gifts with them back to Eljigidei which were to be sent on to Guyuk, while the initial letter was forwarded back to F
