Su Jian (蘇檢) (died March 6, 903), courtesy name Shengyong (聖用), was an official of the Chinese Tang Dynasty, serving briefly as chancellor from 902 to 903, while Emperor Zhaozong was under the physical control of the warlord Li Maozhen the military governor (Jiedushi) of Fengxiang Circuit (鳳翔, headquartered in modern Baoji, Shaanxi) and Li's eunuch allies, led by Han Quanhui. After Li Maozhen was forced to surrender Emperor Zhaozong to another warlord, Zhu Quanzhong, the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan), Su was forced to commit suicide. Background Little is known about Su Jian's family background, as he did not have a biography in either of the official histories of the Tang Dynasty, the Old Book of Tang and the New Book of Tang, and it is not known when or where he was born. According to the table of the chancellors' family trees in the New Book of Tang, Su's family was described as "from Wugong". His grandfather was named Su Tiao (蘇迢), and his father was named Su Meng (蘇蒙); neither was listed with any official titles. Little is also known about Su's early career. According to the biography of Su's chancellor colleague Lu Guangqi in the New Book of Tang, Su had, at one point, served as the prefect of Yang Prefecture (洋州, in modern Hanzhong, Shaanxi). When, in late 901, then-reigning Emperor Zhaozong was forcibly taken by the eunuchs led by Han Quanhui to Fengxiang, then ruled by the eunuchs' ally Li Maozhen, with most of the imperial officials remaining at the capital Chang'an, Su and another prefect, Wei Yifan, went to Fengxiang. Su was thereafter made Zhongshu Sheren (中書舍人), a mid-level official at the legislative bureau (中書省, Zhongshu Sheng), while, at Li's recommendation, Wei was made a chancellor. As chancellor In spring 902, apparently at Li Maozhen's recommendation, Wei Yifan was made chancellor, even though the commission came at Emperor Zhaozong's disgust. However, several months later, Wei's mother died, and he had to leave governmental service to observe a mourning period. The eunuchs initially wanted the imperial scholar Yao Ji to be made chancellor, but Yao declined the commission at the advice of his imperial scholar colleague Han Wo, who cited the likelihood of eventual retaliation by Zhu Quanzhong, the military governor of Xuanwu Circuit, who had by that point put Fengxiang Circuit's capital Fengxiang Municipality under siege to
