After Empress Zhang was elevated by Emperor Emperor Suzong of Tang, she maintained strong imperial favor and gradually expanded her role into state affairs; She also had access to the state treasuries and storage warehouses within the palace, relying on the favor and permission of the emperor, and she would take from them whenever she wished, in whatever amount she desired. In close cooperation with the powerful eunuch Li Fuguo, she effectively controlled significant authority within the inner palace (禁中), forming a core power bloc in the court. In her private quarters, many petitioners and visitors—including officials, courtiers, and individuals seeking favors—would approach her directly. Through frequent informal petitions and private channels (私謁), she influenced key decisions such as official appointments and administrative matters, bypassing normal bureaucratic procedures and thereby disrupting the established political order. As her requests became increasingly excessive, Emperor Suzong gradually grew dissatisfied. However, due to the constraints of the inner court power structure and his reliance on these internal forces, he was unable to effectively restrain or remove her influence. After Empress Zhang became empress, she tried to have her son Li Shao, who was said to be only a few years old, made crown prince. Emperor Suzong, who favored Li Chu as crown prince, could not decide immediately, but after consulting with the official
Li Kui, he created Li Chu crown prince later in 758 and changed Li Chu's name to Li Yu. She nevertheless thereafter tried to have Li Yu replaced with Li Shao, but after Li Shao died in 760, because Li Tong was even younger, Li Yu's position was secure. Throughout the years, Empress Zhang and Li Fuguo's alliance held, and in 760, they together persuaded Emperor Suzong to acquiesce to forcibly moving Emperor Xuanzong, who was then at his preferred subsidiary palace Xingqing Palace (興慶宮), back to the main palace, and exiling Emperor Xuanzong's staff members. However, as of spring 762, when both Emperors Xuanzong and Suzong were seriously ill, Empress Zhang and Li Fuguo had begun to be rivals. (During Emperor Suzong's illness, at one point, to display her love for him, she used her blood to write Buddhist
sutras in order to seek blessing for him.) She summoned Li Yu and tried to persuade him to join her in killing Li Fuguo and his ally
Cheng Yuanzhen. Li Yu declined, and she instead tried to persuade his younger brother Li Xi (李係) the Prince of Yue, to join her. Li Xi agreed. (Her biographies in
Old Book of Tang and the
New Book of Tang also indicated that she offered to make Li Xi emperor.) She and Li Xi thereafter had the eunuch Duan Hengjun (段恆俊) select some 200 strong eunuchs, ready to ambush Li Fuguo and Cheng. On May 14, Empress Zhang issued an order in Emperor Suzong's name, summoning Li Yu. Cheng found out and informed Li Fuguo, who intercepted Li Yu at the palace gate and then escorted him to the camp of the imperial guards under Li Fuguo's command. The guards under LI Fuguo's command then entered the palace and arrested Empress Zhang and Li Xi; the other eunuchs and
ladies in waiting fled, leaving Emperor Suzong without care. On May 16, Emperor Suzong died, and Li Fuguo thereafter executed Empress Zhang and Li Xi, as well as Li Xian the Prince of Yan, and then declared Li Yu emperor (as Emperor Daizong). Many of her associates were executed, while Zhang Qing, Zhang Qian, and her uncle Dou Lüxin (竇履信) were exiled. She was posthumously demoted to commoner rank. ==Notes and references==
