Han Jian (Zhenguo warlord)

Han Jian (韓建) (855-August 15, 912), courtesy name Zuoshi (佐時), was a warlord late in the Chinese dynasty Tang Dynasty, who eventually became a subject of the succeeding Later Liang. He is most well known for having had Emperor Zhaozong of Tang under his control at his power base at Hua Prefecture (華州, in modern Weinan, Shaanxi) from 896 to 898 and slaughtering the imperial princes while Emperor Zhaozong was there.

Han Jian was born in 855, during the reign of Emperor Xuānzong of Tang. He was from Xu Prefecture (許州, in modern Xuchang, Henan). His ancestors, including his father Han Shufeng (韓叔豐), had served for generations in the army. When Qin Zongquan took over Cai Prefecture (蔡州, in modern Zhumadian, Henan) in 880, he encouraged people to join his army, and Han Jian did.

In 881, when the eunuch general Yang Fuguang was able to persuade Zhou Ji the military governor (Jiedushi) of Zhongwu Circuit (忠武, headquartered at Xu Prefecture) to renounce his allegiance to Huang Chao — a major agrarian rebel who had captured the Tang capital Chang'an, forced then-reigning Emperor Xizong (Emperor Xuānzong's grandson) to flee to Chengdu, and declared himself the emperor of a new state of Qi — and return to the Tang fold, Yang also persuaded Qin to send forces to contribute to the war efforts against Huang's Qi state. Yang organized his army into eight corps, commanded by Lu Yanhong, Jin Hui (晉暉), Wang Jian, Han Jian, Zhang Zao (張造), Li Shitai (李師泰), and Pang Cong (龐從) respectively. Han thereafter served under Yang.
