Dou Wu
In 166 CE, the official Li Ying (李膺) was accused by palace eunuchs of plotting treason with students at the Imperial University and associates in the provinces who opposed the eunuchs. Emperor Huan was furious, arresting Li and his followers, who were only released from prison the following year due to pleas from the General-in-Chief Dou Wu (d. 168 CE) (Emperor Huan's father-in-law). However, Li Ying and hundreds of his followers were proscribed from holding any offices and were branded as partisans (黨人).
