Zhang Jianzhi
By early 705, Wu Zetian was seriously ill, and the chancellor Zhang Jianzhi, believing that the Zhangs' power threatened Li Xian's succession, entered into a coup plot with the other officials Cui Xuanwei, Jing Hui, Huan Yanfan, and Yuan Shuji. They rose on February 20 and went to see Li Xian and, after receiving his assent, took their forces into the palace and killed Zhang Yizhi and Zhang Changzong at Yingxian Courtyard (迎仙院); their brothers Zhang Changqi, Zhang Tongxiu, and Zhang Changyi were also killed, and the five men's heads were hung at Tianjin Bridge (天津橋), one of the entries to Luoyang. The officials then forced Wu Zetian to yield the throne to Li Xian (as Emperor Zhongzong), ending Zhou Dynasty and restoring Tang Dynasty.
