Ong Keo (องค์แก้ว) led Austroasiatic-speaking minorities (formerly called Mon-Khmer) in what in Thailand was called the Holy Man's Rebellion, where it was a widespread but short-lived cause. Against French and Lao forces, however, Ong Keo continued the struggle until his murder in 1910. After his death, fighting still continued under his successor Ong Kommandam until at least 1937. Local legend holds that Ong Keo survived the murder attempt and lived until the early 1970s.
