The Yuan Dynasty (元朝/Yuan Chao/Yüan Ch’ao): Foreign Rulers and Sinicization
The conquests of Genghis Khan are known throughout the world. What is lesser known is the impact that the short-lived Mongol empire would have on China. Although the Mongols were able to conquer one of the largest regions in history, stretching from the Korean Penninsula to Ukraine by 1259 BCE, the size of their empire made it basically ungovernable for an essentially nomadic peoples. The rapid fragmentation of the Mongol Empire forced the Mongolian tribes back toward the east, and they were able to maintain political control over a much smaller region for the next hundred years. The region they held included most of modern-day China, Mongolia and Korea.
