Helian Duo

Helian Duo (赫連鐸) (died 894) was an ethnically-Tuyuhun warlord in late Tang Dynasty. He had a long-running enmity with the Shatuo chieftain Li Keyong, and was killed by Li Keyong in 894.

Little is known about Helian Duo's background, including his birth year, other than that, as of the time of Emperor Yizong, he was then a Tuyuhun chief and carried the Tang-bestowed title of commandant of Yin Mountains. Later, when Tang imperial forces had to battle a rebellion led by Pang Xun at Xu Prefecture (徐州, in modern Xuzhou, Jiangsu), Helian participated in the campaign.

In 878, the Shatuo chieftain Li Guochang and his son Li Keyong rose against the rule of Emperor Yizong's son and successor Emperor Xizong at Zhenwu (振武, headquartered in modern Hohhot, Inner Mongolia) and Datong (大同, headquartered in modern Datong, Shanxi) Circuits, respectively. Emperor Xizong ordered Helian, as well as the Tang military governors (Jiedushi) Li Jun (李均) the military governor of Zhaoyi Circuit (昭義, headquartered in modern Changzhi, Shanxi) and Li Keju the military governor of Lulong Circuit (盧龍, headquartered in modern Beijing), Helian's fellow Tuyuhun chieftain Bai Yicheng (白義誠), and the Sage (薩葛) chieftain Mi Haiwan (米海萬) to attack Li Guochang and Li Keyong. In summer 879, when Li Keyong was personally defending against an attack by Li Keju, Li Keyong left his officer Gao Wenji (高文集) in command of his base at Shuo Prefecture (朔州, in modern Shuozhou, Shanxi). Helian persuaded Gao to submit to the new Tang-commissioned military governor of Datong, Li Zhuo (李琢), and Gao surrendered with the Shatuo chieftain Li Youjin (李友金), Mi, and Shi Jingcun, after arresting fellow officer Fu Wenda (傅文達). When Li Keyong tried to return to Shuo to attack Gao, Li Keju defeated him. Li Zhuo and Helian then attacked Li Guochang at Wei Prefecture (蔚州, in modern Zhangjiakou, Hebei) and defeated him as well. Li Guochang and Li Keyong were forced to flee to the Dada (達靼) tribe, then near the Yin Mountains. For his accomplishments against the Shatuo, Helian was made the prefect of Datong's capital Yun Prefecture (雲州) and the defender of Datong Circuit.
