I honestly had no idea about the French fascination with the Mongols. People tend to admire people who have traits they aspire to. I wonder if this stems from France, being a major imperial power at the time, admiring the Mongols as an imperial power. This timeline coincides with the Crusades with, which the article talks about at length. I find the Crusades fascinating because they've shaped the modern world in so m…
Crusades in middle east started as an attempt of Eastern Roman empire (although they just called it Roman empire / Basileia Romaion) to recover from recent advances of Muslim invaders in Anatolia (modern Turkey). But turned into an overwhelmingly religious effort in the west. The first crusade especially was largely ill organized and chaotic affair. Where on one end of the spectrum you had nobles arriving with somewhat well equipped forces and idea of what to do, and on the other you had pilgrims, with whatever they just picked up in their hands and not answering commands of anyone, but their priest.
The economic side of things came into play after the process started and gradually became dominant. But it didn't start like it.
Finally. Interest of France in Mongols can be easily explained precisely by the influence crusades had on French and other Christian elites in Europe. The initial victory of 1st Crusade was followed by a series of setbacks. Muslims gradually begun to push crusaders out, the fact that crusaders started to fight amongst themselves helped a lot.
And then mongols arrived, almost from nowhere, crushed one of most powerful Muslim states at the time, and didn't stop there. It did seem like an immense opportunity, and in a way it was. If French, or someone else in Christendom, could convince khans that some form of cooperation is possible, or even better, if Mongols converted to Christianity, there would be a decent chance to not only save Jerusalem, but to move on to Egypt (still majority Christian).
