Ming dynasty The Ming dynasty was the ruling dynasty of China – then known as the Empire of the Great Ming – for 276 years (1368–1644) following the collapse of the Mongol-led Yuan dynasty. The Ming, described by Edwin O. Reischauer, John K. Fairbank and Albert M. Craig as "one of the greatest eras of orderly government and social stability in human history", was the last imperial dynasty in China ruled by ethnic Han Chinese. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the Shun dynasty, soon replaced by the Manchu-led Qing dynasty), regimes loyal to the Ming throne – collectively called the Southern Ming – survived until 1683.
Guo Kan Guo Kan or Kuo K'an (), (1217–1277) was a famous general of Han descent who served the Mongol Khans in their Western conquests and the conquest of China itself. He was descended from a lineage of Chinese generals. Both his father and grandfather had served the Khan, while his forefather Guo Ziyi, a famed general of the Tang Dynasty. He was not a senior Mongol commander but was in charge of Chinese artillery units under the Mongol Empire. He was one of the foreign legions that served the Mongol Empire, and some of the later conquests of the Mongols were done by armies under his command. The biography of this Han commander in the "Yuan Shi" ("History of Yuan") said that Guo Kan's presence struck so much fear in his foes that they called him the "Divine Man".
