After the French armies captured the city of Huế and the Purple Forbidden City fell to the French, the court regents Nguyễn Văn Tường and Tôn Thất Thuyết took the young Emperor Hàm Nghi and escaped from the Purple Forbidden City of Huế, and took him to the mountains as the figurehead of a revolutionary movement against the French. To take away the legitimacy of Hàm Nghi, general de Courcy and résident de Champeaux of France asked the empress dowager Nghi Thiên to enthrone prince Nguyễn Phúc Ưng Kỷ (Hàm Nghi's elder half brother). On 19 September 1885, Prince Nguyễn Phúc Ưng Kỷ had to go to the governor of Annam to attend his coronation; he became the ninth emperor of Đại Nam with the era name of Đồng Khánh.
