Xuan of Chen (c640). Scroll detail. Ink, color on silk. 50 x 70. Attributed. Emperor Xuan of Chen, personal name Chen Xu, courtesy name Shaoshi, nickname Shili, was an emperor of the Chen dynasty of China. He seized the throne from his nephew Emperor Fei in 569 and subsequently ruled the state for 13 years. He was considered to be a capable and diligent ruler, who at one point militarily expanded at the expense of Northern Qi. After Northern Qi fell to Northern Zhou in 577, however, Chen was cornered, and soon lost the gains it had previously made against Northern Qi. Emperor Xuan died in 582, leaving the state in the hands of his incompetent son Chen Shubao, and by 589, Chen would be destroyed by Northern Zhou's successor state Sui dynasty. Chen Xu was born in 530, as the second son of Chen Daotan, a commander in the Liang Dynasty palace guards. His mother's name is not recorded in history. Chen Daotan died in 548 or 549, while commanding the guards in resisting a siege of the palace at the capital Jiankang by the rebel general Hou Jing. After the palace fell to Hou in 549, Chen Xu's older brother Chen Qian and cousin Chen Chang were imprisoned by Hou, because Chen Chang's father, the general Chen Baxian, had joined forces with Wang Sengbian, a general under the command of Xiao Yi the Prince of Xiangdong in resisting Hou. It is unclear whether Chen Xu was imprisoned as well. In 551, Wang, with Chen's assistance, defeated Hou and recaptured Jiankang. Xiao Yi subsequently declared himself emperor, but set up his capital at Jiangling rather than returning to Jiankang, which he put under the command of Wang. As part of this alignment, Chen Baxian was given the post of defending Jingkou. Emperor Yuan then summoned Chen Chang and Chen Xu to Jiangling to serve in his administration, and also to serve as hostages. Both were given mid-level positions. He also gave Chen Xu a wife, his niece Liu Jingyan. In 554, rival Western Wei attacked Jiangling and captured it, executing Emperor Yuan around the new year 555. Chen Xu and Chen Chang were taken to the Western Wei capital Chang'an as honored captives, while Lady Liu and their son Chen Shubao were left at Rangcheng. Wang and Chen Baxian initially wanted to make Emperor Yuan's son Xiao Fangzhi the Prince of Jin'an emperor, but after military pressure from Northern Qi, in summer 555, Wang agreed to make Northern Qi's favored candidate Xiao Yuanming emperor instead, a decision that Chen disagreed with. In fall 555, he made a surprise attack on Jiankang, killing Wang and deposing Xiao Yuanming, making Xiao Fangzhi emperor instead. In 557, he had Emperor Jing yield the throne to him, establishing Chen Dynasty as its Emperor Wu. Chen Xu's brother Chen Qian was created the Prince of Linchuan, and while Chen Xu was still then detained by Western Wei, Emperor Wu remotely created him the Prince of Shixing, to inherit the title that Emperor Wu posthumously created his father Chen Daotan. Emperor Wu died in 559, and because Chen Chang was still detained at Chang'an as well, Chen Qian took the throne. Because Chen Xu was not available to offer sacrifices to their father Chen Daotan, Emperor Wen created his own son Chen Bomao the Prince of Shixing instead, changing Chen Xu's title to Prince of Ancheng. In 560, Western Wei's successor state Northern Zhou began to make overtures to Chen, offering to return Chen Xu. In 562, after Emperor Wen gave Northern Zhou the city of Lushan in exchange, Chen Xu was allowed to return to Chen. Initially, Princess Liu and Chen Shubao were not returned, but after further negotiations by Emperor Wen, they were returned as well. Chen Xu quickly became one of his brother Emperor Wen's key subordinates. For example, in spring 562, when the warlord Zhou Di rebelled, Emperor Wen initially sent the general Wu Mingche against Zhou, but when Wu was unable to defeat Zhou, Emperor Wen sent Chen Xu to replace Wu. Over the next few years, Chen Xu continued to be promoted, although he was temporary relieved of several of his posts in 565, when his associate Bao Sengrui, in reliance of their close relationship, was acting inappropriately, and was accused of such impropriety by the official Xu Ling. In spring 566, Emperor Wen was seriously ill, and Chen Xu, along with the other key officials Dao Zhongju, Kong Huan, Yuan Shu, and Liu Shizhi, attended to him. As Emperor Wen believed his crown prince Chen Bozong to be weak in personality, he offered to pass the throne to Chen Xu, but Chen Xu, weeping bitterly, declined, and the move was also opposed by Dao and Kong, and Emperor Wen did not alter his succession order. Emperor Wen died soon thereafter, and Chen Bozong took the throne as Emperor Fei.
