Bocheonism (Korean: 보천교; RR: Bocheongyo; MR: Pochonkyo, "religion of the vault of heaven/firmament") was one among more than 100 new religious movements of Korea of the family of religions called Jeungsanism, rooted in Korean shamanism[1] and recognizing Gang Il-sun (Kang Jeungsan) as the incarnation of Sangje, the Supreme God.
It was founded by Cha Gyeong-seok (1880–1936) on Ibam Mountain in Daeheung-ri, Ibam-myeon, Jeongeup, North Jeolla Province, in the year 1911.
Cha Gyeong-seok was originally a Donghak (Cheondoist) priest, who converted to Jeungsanism after meeting Gang Il-Sun.
[2] Cha continued under the name Bocheon-gyo, which was adopted in 1921, at a great ritual held in Hamyang County, South Gyeongsang Province.
Branches of Bocheonism are also credited with encouraging local culture in the Jeongeup region, including the pungmulgut performance tradition.
