Wenzong

emperor of Tang dynasty
Also known as: Li Ang, Wen-tsung

Wenzong (born 809, China—died 840, China) was the temple name (miaohao) of the 15th emperor (reigned 827–840) of the Tang dynasty (618–907) of China. He attempted unsuccessfully to free the court from the influence of the palace eunuchs, who had usurped much of the imperial power. His carefully laid plots against the eunuchs all misfired, resulting in the Sweet Dew Incident of 835, in which three of his chief ministers and several other officials were slaughtered. The power of the eunuchs was greatly enhanced; they even dared assassinate an heir apparent of whom they did not approve.
