The Holy Man's Rebellion (Thai: กบฏผู้มีบุญ), took place between March 1901 and January 1936. It started when supporters of the religious movement initiated an armed rebellion against French Indochina and Siam, aiming at installing their leader, sorcerer Ong Keo, as ruler of the world. By 1902 the uprising was put down in Siam, continuing in French Indochina until being fully suppressed in January 1936.
