Đồng Khánh
Before Emperor Đồng Khánh's era came the eras of Emperor Thành Thái and Emperor Duy Tân, both of whom were exiled by the French for their resistance to the colonial regime. After this trouble, the French decided to enthrone Bửu Đảo as he was the son of the monarch who was the most submissive Nguyễn collaborator with the colonial regime, standing with the French colonizers and opposing any independence movements, Emperor Đồng Khánh.
