窦武
The Disasters of the Partisan Prohibitions (黨錮之禍) refers to two incidents in which a number of Confucian scholars who served as officials in the Han imperial government and opposed to powerful eunuchs, and the university students in the capital Luoyang who supported them (collectively referred to by the eunuchs as "partisans" (黨人, "dangren"), were imprisoned. Some were executed; some were released but lost their civil rights. The first incident (in 166) was largely bloodless, but the second incident (in 169), which came after the Confucian scholars Dou Wu (the father of Empress Dowager Dou) and Chen Fan were defeated by eunuchs in a physical confrontation, saw a large number of the partisans lose their lives. The restrictions on civil liberties imposed on the surviving partisans were not lifted until 184 when Emperor Ling was concerned that the partisans would join the Yellow Turban Rebellion.
