Sun Ru

Sun Ru (孫儒) (died July 3, 892), formally the Prince of Le'an (樂安王), was a warlord late in the Chinese dynasty Tang Dynasty who initially served as a general under the pretender emperor Qin Zongquan. After Qin's defeat, he nominally submitted to Tang imperial authority and contended for control of the central-lower Yangtze River region with Yang Xingmi; he was eventually defeated by Yang and executed. His subordinate Ma Yin was the eventual founder of the Five Dynasties and Ten Kingdoms period state Chu.

It is not known when Sun Ru was born. His family was from Henan County, one of the two counties making up the Tang Dynasty eastern capital Luoyang. At some point, he became a low-level officer at Zhongwu Circuit (忠武, headquartered in modern Xuchang, Henan), where he befriended fellow officer Liu Jianfeng. Later, during the rebellion by the major agrarian rebel Huang Chao, Sun served under the command of Qin Zongquan.

By 884, Huang had been defeated and killed, but Qin, who then controlled Fengguo Circuit (奉國, headquartered in modern Zhumadian, Henan) as its military governor (Jiedushi), then became a rebel himself against Emperor Xizong of Tang. As of late 884, Qin was sending a number of his officers to attack or seize territory around his. As part of Qin's campaigns, Sun seized Luoyang, Meng Prefecture (孟州, in modern Jiaozuo, Henan), Shan Prefecture (陝州, in modern Sanmenxia, Henan), and Guo Prefecture (虢州, in modern Sanmenxia). In summer 885, however, he was again battling the Tang defender of Luoyang, Li Hanzhi, for control of Luoyang. It was said that while Li initially abandoned Luoyang after running out of food supplies, Sun only occupied Luoyang for about a month, before burning the palaces, government offices, and houses, and leaving Luoyang after plundering it, allowing Li to again occupy Luoyang.
