窦武
After Emperor Huan's death, at the urging of the Grand Tutor (太傅) Chen Fan (陳蕃) (d. 168 CE), Dou Wu presented a memorial to the court in June 168 CE denouncing the leading eunuchs as corrupt and calling for their execution, but Empress Dowager Dou refused the proposal. This was followed by a memorial presented by Chen Fan calling for the heads of Hou Lan (d. 172 CE) and Cao Jie (d. 181 CE), and when this too was refused Dou Wu took formal legal action which could not be ignored by the court. When Shan Bing, a eunuch associate of Chen and Dou's, gained a forced confession from another eunuch that Cao Jie and Wang Fu (王甫) plotted treason, he prepared another damning written memorial on the night of 24–25 October which the opposing eunuchs secretly opened and read. Cao Jie armed Emperor Ling with a sword and hid him with his wet nurse, while Wang Fu had Shan Bing killed and Empress Dowager Dou incarcerated so that the eunuchs could use the authority of her seal.
