宇文述
Yuwen Shu (宇文述; died 616), courtesy name Botong (伯通), formally Duke Gong of Xu (許恭公), was an official and general of the Sui Dynasty of China. 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, but was soon captured and killed. Another son of Yuwen Shu, Yuwen Shiji, however, was a friend of Tang Dynasty's founder Li Yuan (Emperor Gaozu), and after Li Yuan established Tang remained an influential official.
