张昌宗
In spring 705, with Wu Zetian being ill, Jing entered into a plot with a number of officials and generals, including Zhang Jianzhi, Cui Xuanwei, Huan Yanfan, and Yuan Shuji, to kill her lovers Zhang Yizhi and Zhang Changzong. With agreement from Li Xian the Crown Prince (Wu Zetian's son), they acted on February 20, killing Zhang Yizhi and Zhang Changzong, and then surrounding Wu Zetian. While they allowed her to retain the title of "emperor," they had her put under house arrest at the secondary palace Shangyang Palace (上陽宮) and forced her to yield the throne to Li Xian, who was formerly emperor, and he was restored to the throne (as Emperor Zhongzong). Two days later, Emperor Zhongzong was formally restored.
