Yuwen Shu
Yuwen Shu (; died 20 November 616),
courtesy name Botong (伯通), formally
Duke Gong of Xu (許恭公), was a Chinese military general and politician of the
Sui dynasty. He was a confidant of
Emperor Yang (Yang Guang) and was instrumental in Yang Guang's displacement of his brother
Yang Yong as
crown prince; therefore, after Yang Guang became emperor, Yuwen Shu became exceedingly powerful and was one of two generals who spearheaded Yangdi's efforts in the
Goguryeo-Sui Wars. His son
Yuwen Huaji later led a coup against Emperor Yang in 618 and, after killing Emperor Yang, briefly claimed imperial title in 619 and founded the state of Xu, but was soon captured and killed. Another son of Yuwen Shu,
Yuwen Shiji, however, was a friend of the
Tang dynasty's founder
Li Yuan (Emperor Gaozu), and after Li Yuan established Tang remained an influential official.
