竇武
Emperor Ling's reign saw another repetition of corrupt eunuchs dominating the eastern Han central government, as was the case during his predecessor's reign. Zhang Rang, the leader of the eunuch faction (十常侍), managed to dominate the political scene after defeating a faction led by Empress Dowager Dou's father, Dou Wu, and the Confucian scholar-official Chen Fan in 168. After reaching adulthood, Emperor Ling was not interested in state affairs and preferred to indulge in women and a decadent lifestyle. At the same time, corrupt officials in the Han government levied heavy taxes on the peasants. He exacerbated the situation by introducing a practice of selling political offices for money; this practice severely damaged the Han civil service system and led to widespread corruption. Mounting grievances against the Han government led to the outbreak of the peasant-led Yellow Turban Rebellion in 184.
