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.
Zhang Xiaozhong Zhang Xiaozhong (張孝忠) (730 – April 30, 791), né Zhang Alao (張阿勞), formally Prince Zhenwu of Shanggu (上谷貞武王), was a general of the Chinese Tang Dynasty, of Xi extraction. Initially he served the rebel state Yan, during the Anshi Rebellion, and later served the warlord Li Baochen. After Li Baochen's death he joined the Imperial cause, giving the Imperial army a foothold north of the Yellow River in spite of being surrounded by semi-independent warlord realms.
