Han Jian () (died 883), formally the Prince of Changli () or Prince of Wei Commandery (), was a warlord late in the Chinese Tang Dynasty, who controlled Weibo Circuit (魏博, headquartered in modern Handan, Hebei). When imperial authority disintegrated in the aftermaths of the Huang Chao rebellion, Han tried to conquer several nearby circuits by force, but after his endeavors failed, his subordinates supported his officer Le Xingda to replace him. Han then either died in distress or was killed. Background It is not known when Han Jian was born. His father Han Yunzhong (who was then named Han Junxiong) was a long-time officer at Weibo Circuit and seized control of the circuit when the soldiers mutinied in 870 against then-military governor (Jiedushi) He Quanhao and killed He Quanhao because of He Quanhao's harsh discipline. Han Jian became deputy military governor after his father became military governor. Initial service as military governor of Weibo After Han Yunzhong died in 874, the Weibo soldiers supported Han Jian to succeed him, and then-ruling Emperor Xizong agreed, making Han Jian acting military governor initially, and then full military governor in 875. He gave Han Jian the honorary chancellor designation of Tong Zhongshu Menxia Pingzhangshi () in 876, and Shizhong () in 882. He was also either created the Prince of Changli (per the Old Book of Tang) or the Prince of Wei Commandery (per the New Book of Tang). Attempts to conquer nearby circuits, failure, and death By that point, however, Tang imperial authority had collapsed in the aftermaths of the major agrarian rebellion led by Huang Chao — who had captured the Tang imperial capital Chang'an and claimed the throne as the emperor of a new state of Qi, forcing Emperor Xizong to flee to Chengdu — and generals were freely attacking each other over territory. In fall 882, Han Jian, wanting to seize nearby Heyang Circuit (河陽, headquartered in modern Jiaozuo, Henan), took 30,000 soldiers and attacked Heyang's military governor Zhuge Shuang at Xiuwu (修武, in modern Jiaozuo). Zhuge abandoned Xiuwu, and Han left forces to defend Xiuwu, before turning north to pillage Xing (邢州, in modern Xingtai, Hebei) and Ming (洺州, in modern Handan) Prefectures (both belonging to Zhaoyi Circuit (昭義, headquartered in modern Changzhi, Shanxi)); he then returned to Weibo. Later in the year, Han attacked Yun Prefecture (鄆州, in modern Tai'an, Shandong), the capital of Tianping Circuit
