Hun Jian (simplified Chinese: 浑瑊; traditional Chinese: 渾瑊; pinyin: Hún Jiān; 736 – January 1, 800), né Hun Jin (渾進), formally Prince Zhongwu of Xianning (咸寧忠武王), was a general of the Chinese dynasty Tang Dynasty of Tiele extraction. He was most-well known for his battles to protect Emperor Dezong during Zhu Ci's rebellion.
Hun Jian (who was initially named Hun Jin, but who subsequently changed his name to Hun Jian after he later became prominent) was born in 736, during the reign of Emperor Xuanzong. His ancestors were chieftains of the Hun tribe (渾), one of the nine main constituent tribes of the Tiele Confederation. After the Tiele tribes largely submitted to Tang rule during the reign of Emperor Xuanzong's great-grandfather Emperor Taizong, the Hun tribe was incorporated as a border prefecture, the Gaolan Prefecture (臯蘭州). Hun Jian's great-great-grandfather Hun Atanzhi (渾阿貪支) was given the title of prefectural prefect of Gaolan. His great-grandfather Hun Yuanqing (渾元慶), grandfather Hun Dashou (渾大壽), and father Hun Shizhi (渾釋之) all carried the title of commandant at Gaolan Prefecture.
Hun Shizhi served in the army at Tang's Shuofang Circuit (朔方, headquartered in modern Yinchuan, Ningxia) and, for his repeated accomplishments there, was made a general and created the Prince of Ningshuo. In 746, when Hun Jian was 10, he began to follow his father on fall tours to defend the Tang border. His father's superior, the military governor (Jiedushi) of Shuofang, Zhang Qiqiu (張齊丘), saw him, and jokingly asked him, "Did you come with your wet nurse?" Yet, even at his young age, he had battlefield accomplishments that year. In 748, he served under his father in defeating the Helu (賀魯) tribe and, by this point, he was said to be braver than the other soldiers in the army. When the ethnically Tujue general Li Xianzong (李獻忠) rebelled in 752, the military governor of Shuofang at that time, An Sishun, had Hun Jian command troops against Li Xianzhong, and subsequently, he was promoted.
