Đồng Khánh
While the emperor Tự Đức was alive, Prince Quang Thái was placed under house arrest with his family for having connections with those who opposed him. When the emperor Đồng Khánh died, however, the French colonial authorities and the high-ranking mandarins decided that Quang Thái was the ideal successor and enthroned him as the new Vietnamese emperor, Emperor Thành Thái.
