Qiu Shiliang
In 835, the infamous "Sweet Dew Incident" occurred during the reign of Emperor Wenzong. A palace coup designed by Li Xun (the prime-minister) and Zheng Zhu (the military governor of Feng Xiang) support of Wenzong's effort to overthrow the eunuchs failed. The eunuchs, led by Qiu Shiliang, slaughtered the clans of many high officials and chief ministers. A great many other innocent people were killed in connection with this event. The eunuchs whose power had been growing out of control now completely dominated the Emperor and the affairs of state.
