武承嗣
In 690, Zhou suggested that the Li clan members be stripped of imperial clan status, and Empress Dowager Wu did so. He also falsely accused the chancellor Wei Fangzhi, who was subsequently exiled and executed in exile. Then, at the instigation of Empress Dowager Wu's powerful nephew Wu Chengsi, he accused Emperor Gaozong's sons by concubines, Li Shangjin () the Prince of Ze and Li Sujie the Prince of Xu of treason. Li Sujie was strangled, while Li Shangjin committed suicide.
