The Mongol Conquests marked one of the most pivotal periods in medieval history, with one man at the center. Emperor Genghis Khan famously united the Mongol tribes and led them on a path of bloodthirsty conquest that spanned a century. He is known as a monster who massacred millions. The true legacy of Genghis Khan is much more complex. His strategic prowess, psychological warfare, and unique battlefield tactics enabled the Mongols to conquest much of 13th-century Asia with ease. The Mongol Empire's vast expansion was fueled by Genghis Khan's brilliant leadership.
