王叔文
Emperor Dezong died in 805, and Li Song, who was by that point himself seriously ill, became emperor (as Emperor Shunzong). Due to Emperor Shunzong's illness, the government was, for a while, effectively run by Wang Shuwen, Wang Pi, Emperor Shunzong's concubine Consort Niu, and the eunuch Li Zhongyan (). However, Wang Shuwen soon lost power later that year as power became concentrated in the hands of Emperor Shunzong's crown prince Li Chun.
