Mongols: Good or Bad?
Sometimes we see Genghis Khan and the Mongol Empire and they're really bad - they attack defenseless cities and kill thousands of people and make piles of their skulls. Other times, the Mongols seem like they were good - the Mongol Empire made Eurasia safe to travel around in, and helped spread the use of paper and glass and steel and sugar and other important inventions from China to West Asia and from West Asia to China. Which is true? Can they both be true at the same time?
