咸宜帝
Phan rallied to the cause of the boy Emperor Hàm Nghi—the fourth monarch in little over a year—after an abortive royal uprising at Huế in 1885. Thuyet and fellow regent Nguyễn Văn Tường had enthroned Hiệp Hòa after disposing of Dục Đức. However, the new emperor was wary of the regents' behaviour and attempted to avoid their influence, leading Thuyet to organise his execution. The teenage Kiến Phúc ascended the throne, but was poisoned by his adoptive mother Học Phi—one of Tự Đức's wives—whom he caught having intercourse with Tuong. Kien Phuc was thus replaced by his 14-year-old brother Hàm Nghi. In the meantime, the French concluded that the regents were causing too much trouble and had to be disposed of.
