Liu Jun (劉濬),courtesy nameBoshen (伯深), was an official of theChineseFive Dynasties and Ten Kingdoms Period stateSouthern Han, at one point serving as achancellor.
It is not known when Liu Jun was born. His fatherLiu Chongwang was a prominent late-Tang official and served as achancellor during the reign ofEmperor Zhaozong. Several of his uncles, including Liu Chongwang's older brother Liu Chonggui (劉崇龜), were also prominent.[1][2]
During Emperor Zhaozong's reign, the realm was in great turmoil. Sometime after Liu Chonggui's becoming the military governor (Jiedushi) of Qinghai Circuit (清海, headquartered in modernGuangzhou,Guangdong), early in Emperor Zhaozong'sDashun era (890-891), Liu Jun, wanting to avoid the turmoils, followed his uncle Liu Chonggui to Qinghai and became dependent on Liu Chonggui. He remained at Qinghai's capital Guang Prefecture (廣州) after Liu Chonggui's death in the middle of Emperor Zhaozong's Qianning era (894-898).[1]
Liu Chonggui had, in or around 894, commissionedLiu Yin as the defender of Heshui Base (賀水鎮, in modernNanning,Guangxi), and then as the prefect of Feng Prefecture (封州, in modernZhaoqing,Guangdong).[3] Therefore, after Liu Yin subsequently became the military governor of Qinghai, first in an acting capacity in 901[4] and then officially in 904,[5] Liu Yin, in showing gratitude to Liu Chonggui, treated Liu Jun with respect. He invited Liu Jun to serve on his staff, serving withLi Yinheng andNi Shu, often consulting them on key decisions.[1]
In 917, Liu Yin's brother and successorLiu Yan, who had previously been a vassal of Tang's successor stateLater Liang, declared himself emperor of a new state of Yue (later changed to Han, and therefore historically known asSouthern Han).[6] He commissioned Liu Jun as the minister of imperial clan affairs (宗正卿,Zhongzheng Qing) and deputy minister of public works (工部侍郎,Gongbu Shilang). Toward the end of Liu Yan'sQianheng era (917-925), there was a time when Liu Yan mobilized an army and placed it at Chao Prefecture (潮州, in modernChaozhou,Guangdong), preparing to launch it against Southern Han's northeastern neighborMin. Liu Jun found this inadvisable, so he discussed this with the chancellorYang Dongqian. Yang agreed with him and tried to dissuade Liu Yan, to no avail.[1] In 924, Liu Yan led the troops to take up a position between Min's Ting (汀州, in modernLongyan,Fujian) and Zhang (漳州, in modernZhangzhou,Fujian) Prefectures. A Min army attacked him, and he was forced to withdraw.[7] He thus greatly regretted not listening to Yang and Liu Jun.[1]
After Yang died in 936,[1][8] Liu Yan promoted Liu Jun to be chancellor, with the titles ofZhongshu Shilang (中書侍郎) andTong Zhongshu Menxia Pingzhangshi (同中書門下平章事), to replace Yang.[1][9] It was said that Liu Jun was honest and frugal. He often encouraged Liu Yan to love his people and rest his army, in terms that were delicate but firm. He died while serving as chancellor, but the date was not given.[1] (As nothing was said about his serving under Liu Yan's successors, presumably he died before Liu Yan's death in 942.)[10]
