Yang Xiu (Sui dynasty)

Yang Xiu (楊秀) (570s – c.12 April 618^[1]) was an imperial prince of the Sui dynasty. He was a son of Emperor Wen and his powerful wife Empress Dugu, and during most of his father's reign was given great control over the modern Sichuan and Chongqing region. In 602, after accusations were made that Yang Xiu was abusing his power, Emperor Wen removed him from power and reduced him to commoner rank. He was subsequently held under house arrest for the rest of Emperor Wen's reign and the reign of his brother Emperor Yang. In April 618, after the general Yuwen Huaji killed Emperor Yang, he and his co-conspirators briefly considered declaring Yang Xiu emperor, but ultimately decided not to, and instead executed Yang Xiu and his sons.

^ Volume 185 of Zizhi Tongjian indicated that the palace revolt against Yang Guang began on the yimao day of the 3rd month of the 14th year of the Da'ye era of his reign, and that he was killed the next day (i.e. the bingchen day). The date corresponds to 11 Apr 618 on the Julian calendar. Thus, Yang Xiu was killed on or shortly after 11 April 618.
