Emperor Ai of Tang
In 904, Zhu forced Emperor Zhaozong to move the capital from Chang'an to Luoyang, which was even more firmly under his control. Later that year, fearing that the adult Emperor Zhaozong would try to rise against him while he was away on campaigns against other warlords, he had Emperor Zhaozong assassinated. Bypassing Li Yu and the other older princes, he had an edict issued in Emperor Zhaozong's name creating Li Zuo crown prince and changing his name to Li Chu. Shortly after, Li Chu took the throne (as Emperor Ai). Empress He, who survived the assassination, was honored empress dowager.
Administrative divisions of the Tang dynasty
The court made slow progress in stamping out the rebellion due in large extent to the deterioration of central authority. The reigning sovereign Tang Xizong was subject to constant manipulation by eunuch officers like Tian Lingzi. Although the rebellion was finally defeated in 884, the court continued to face challenges posed by the warlords—officially military commissioners who held enormous regional power, including Li Maozhen in Fengxiang (Qizhou, Jingji 京畿), Li Keyong in Taiyuan (Bingzhou, Hedong), Wang Chongrong in Hezhong (Puzhou, Hedong), and Zhu Wen in Bianzhou, Henan. The country was constantly torn by the tug-of-war between the eunuchs and the warlords. The eunuchs used their physical control of the emperor as leverage to stay in power and carry out their agenda. The warlords wanted to purge the court of eunuch influence. Against this hopeless backdrop, the penultimate sovereign of Tang, Zhaozong, ascended the throne in 888, and although a man of lofty ambition, he remained throughout his reign a mere puppet in the machinations of court politics.
