司馬道子
After Emperor Xiaowu's death in 396, Emperor An became emperor, and as he was developmentally disabled, Sima Daozi, as his uncle, served as regent. Sima Daozi was incompetent, and his trusted associates Wang Guobao (王國寶) and Wang Xu (王緒) took the opportunity to become wealthy from corruption. They feared the military powers that Yin Zhongkan and Wang Gong (王恭) the governor of Yan (兗州) and Qing (青州) Provinces (at that time, roughly modern central Jiangsu) possessed and persuaded Sima Daozi to reduce their domains. In response, Wang Gong sent messengers to Yin to discuss a campaign to seek the removal of Wang Guobao and Wang Xu. Huan Xuan, believing that a disturbance would help his cause, encouraged Yin to join Wang Gong's campaign. Wang Gong, believing that Yin would join him, then started the campaign, and quickly intimidated Sima Daozi into executing Wang Guobao and Wang Xu.
