Lê Hoàn
After the assassination of the emperor, Đinh Tiên Hoàng, and the emperor's first son, Đinh Liễn, the third son of the emperor, Đinh Phế Đế, assumed the throne at aged six with the regent Lê Hoàn. During the regency of Lê Hoàn, members of the royal court skeptical of Lê Hoàn's loyalty to the true emperor, such as the Duke of Định Nguyễn Bặc and General Đinh Điền, led an army to the imperial palace in an attempted coup. The failure of the undertaking caused those two figures to be executed.
