仇士良
Emperor Wenzong originally created his son Li Yong crown prince, but after Li Yong died in 838, he was unsure whom to make his successor. Emperor Wenzong's favorite concubine Consort Yang recommended Li Rong, but when Emperor Wenzong consulted the chancellors, Li Jue opposed this proposal. Emperor Wenzong thus, in 839, created Emperor Jingzong's youngest son Li Chengmei the Prince of Chen crown prince. When Emperor Wenzong became seriously ill early in 840, he had his trusted eunuchs Liu Hongyi () and Xue Jileng () summon the chancellors Yang Sifu and Li Jue to the palace, intending to entrust Li Chengmei to them. However, the powerful eunuchs Qiu Shiliang and Yu Hongzhi (), who were not consulted in the decision, opposed Li Chengmei, and despite Li Jue's objection, forged an edict in Emperor Wenzong's name deposing Li Chengmei by claiming that Li Chengmei was too young, and creating Li Chan crown prince instead. Subsequently, Qiu and Yu had soldiers escort Li Chan from his mansion to the palace and, after Emperor Wenzong then died, persuaded Li Chan to order Consort Yang, Li Chengmei, and Li Rong all to commit suicide. After a short mourning period, Li Chan took the throne (as Emperor Wuzong).
