Sima Daozi
Throughout Emperor An's early reign, Sima Dewen received increasingly honorific offices, but had little actual power, as the power was initially in the hands of his uncle, the regent Sima Daozi the Prince of Kuaiji, and later in the hands of Sima Daozi's son Sima Yuanxian. The situation continued after Sima Yuanxian was overthrown by the warlord Huan Xuan in 402.
