About Cheondoism
Cheondoism is a 20th-century Korean religion, based on the 19th-century Donghak religious movement founded by Ch'oe Che-u and codified under Son Pyŏng-Hi. Cheondoism has its origins in the peasant rebellions which arose starting in 1812 during the Joseon dynasty. Cheondoism incorporates elements of Korean shamanism.
