Xianzong realized the growing threat of the Fanzhen (regional military governors) and was determined to rid the empire of all them by waging battles against them. His initial campaigns were quite successful and Xianzong's army defeated Jiedushi (military governors) such as Liu Peng, Yang Huilin in 806 and Li Qi in 807. In 813, military governor Tian Xing quickly surrendered to the Tang army. Xianzong's first set back was in 813 when he failed to defeat military governor Wang Chenzong.

Xianzong's reign briefly stabilized the Tang dynasty from the the destructive forces of the military governors however by the middle of the 9th century, unattentive emperors controlled by corrupt eunuchs gradually weakened the centralized power of the Tang dynasty.

Xianzong himself was murdered by Chen Hongzheng in 820. He was 42.
