Although the Mongols were mighty, they had the shortest rule in Chinese history. ending in 1368 CE. While they ruled China they instituted a social structure that was much different than preceding dynasties. For example, the Yuan Dynasty mingled with foreigners (something dynasties before and after didn't do). The famed Venetian explorer Marco Polo was a huge figure in the Yuan court and held sway with Kublai Khan, his family, and his government. Polo lived among the Yuan court for many years, and became one of Kublai Khan's most important advisers and bureaucrats during his conquest of China.
