John Green teaches you, at long last, about the most exceptional bunch of empire-building nomads in the history of the world, the Mongols! How did the Mongols go from being a relatively small band of herders who occasionally engaged in some light hunting-gathering to being one of the most formidable fighting forces in the world? It turns out Genghis Khan was a pretty big part of it, but you probably already knew that. The more interesting questions might be, what kind of rulers were they, and what effect did their empire have on the world we know today? Find out, as John FINALLY teaches you about the Mongols.
