It seems kind of amazing to me that the Huns and Mongols would both originate from similar parts of the world, both be impressive equestrians, and share many other similarities. I know the Huns don't have the clearest written history and it was about 800-ish years later, but did the Mongols know anything about the Huns, or the Xiongnu, (yes, I know they are not the same thing) when they were building their empire?
There will be always more to be discussed, but I wrote before at least about the total absence of the Huns in Mongolian texts in: Did the Mongols have any knowledge of Attila or the Huns and their origins?
