Duy Tân
In 1916, while France was preoccupied with fighting World War I, Emperor Duy Tân was smuggled out of the Forbidden City with Trần Cao Vân to call upon the people to rise up against the French. However, the secret was revealed and France immediately sent troops there, and after only a few days, they were betrayed and captured by the French authorities. Because of his age and to avoid a worse situation, Emperor Duy Tân was deposed and exiled instead of being killed. Trần Cao Vân and the rest of the revolutionaries were all beheaded. Prince Nguyễn Phúc Vĩnh San was exiled with his father to Réunion Island in the Indian Ocean.
