Hồ Quý Ly
Trần Phế Đế (6 March 1361 – 6 December 1388), given name Trần Hiện, was the tenth emperor of the Trần dynasty who reigned Đại Việt from 1377 to 1388. After his father's death in Battle of Đồ Bàn in January 1377, Phế Đế was enthroned as Đại Việt Emperor by the Retired Emperor Trần Nghệ Tông who acted as Phế Đế's regent during his reign. Fearing the rise of Hồ Quý Ly in royal court, Phế Đế tried to reduce his power but Hồ Quý Ly already got ahead of this plot by a defamation campaign against the Emperor which ultimately made Nghệ Tông decide to dethrone Phế Đế in December 1388. Phế Đế was downgraded to Prince Linh Đức and forced to commit suicide and his supporters in royal court were purged by Hồ Quý Ly faction. The death of Phế Đế marked the last step of Hồ Quý Ly's power seizing from Trần clan.
