Ban continued to serve in the imperial library and at the imperial court throughout the second half of the 1st century AD. During the reign of Emperor Zhang of Han, Ban was promoted to the position of "Marshal of the Black Warrior Gate". Ban later served as a high-ranking literary official under Dou Xian, the brother of Emperor Zhang's empress. Although Dou won prestige for two successful campaigns against the Xiongnu, in AD92 he was suspected by Emperor He of Han of plotting a rebellion and forced to commit suicide. Immediately thereafter, Ban was dismissed from office and arrested by an old rival, Chong Jing, who was serving as the prefect of Luoyang. Ban died in prison that same year at 61 years old.
