Cần Vương movement
The French responded politically to the uprising by pressing ahead with arrangements for entrenching their protectorate in both Annam and Tonkin. They were helped by the fact that there was by no means unanimous support for the Cần Vương movement. The queen mother, Từ Dũ, and other members of the Vietnamese royal family deserted Hàm Nghi and returned to Huế shortly after the uprising began. In September 1885, to undercut support for Hàm Nghi, General de Courcy enthroned the young king's brother Đồng Khánh in his stead. Although many Vietnamese regarded Đồng Khánh as a French puppet king, not all did. One of the most important Vietnamese leaders, Prince Hoàng Kế Viêm, who had been fighting the French for several years in Tonkin, gave his allegiance to Đồng Khánh.
