Yang Su
Yang Su (楊素; 544 - August 31, 606),
courtesy name Chudao (處道), formally
Duke Jingwu of Chu (楚景武公), was a Chinese military general and politician of the
Sui dynasty whose authority eventually became nearly as supreme as the emperor's. Traditional sinologists generally believed that he was involved in the suspected murder of
Emperor Wen in 604, at the behest of Emperor Wen's son
Yang Guang (the later Emperor Yang). His son
Yang Xuangan later rebelled against Emperor Yang in 613 but was defeated and killed, and Yang Su's other sons were also executed.
