Zhang Jianzhi
In 705, a coup led by the officials Zhang Jianzhi, Cui Xuanwei, Jing Hui, Huan Yanfan, and Yuan Shuji killed Zhang Yizhi and Zhang Changzong and overthrew Wu Zetian, restoring Li Xian to the throne. Princess Taiping was said to be involved in the coup, and after Emperor Zhongzong's restoration, he gave her the special title of "Zhenguo Taiping Gongzhu" (鎮國太平公主) — literally "the Princess Taiping who secured the state." In 706, she, along with Emperor Zhongzong's daughters Princesses Changning, Anle (Li Guo'er), Yicheng, Xindu, and Ding'an, and Princess Jincheng (the daughter of Princess Taiping's nephew Li Shouli the Prince of Yong), were allowed to retain staffs, similar to imperial princes. She became one of the powerful women at court, although her power was rivaled by Emperor Zhongzong's wife Empress Wei and Li Guo'er.
