Baekbaekgyo
Baekbaekgyo () was a Korean new religious movement founded by Woo Kwang Hyun. It is associated with a murder incident in the 1930s, during the Japanese colonial period.

History
The movement first started as an offshoot of the religion Baekdokyo (), itself an offshoot of Cheondoism. Baekdokyo was founded in 1899, with its official organization in 1912 and was led by leader Jeon Jeong-ye, an individual who claimed to have received a revelation on Mount Kumgang. Baekdogyo, despite its proselytization projects, was mostly run as a secret organization. It amassed 10,000 followers. After Jeon died in 1919, his second son Jeon Yong-hae and a high priest of the religion at the time named Wookwang Hyun secretly buried a body without telling the believers of the religion. A police investigation regarding the religion surrounding the case of victims of the religion led to the reveal of the secret burial, and Baekdogyo began to decline, and Leehuiryong, another high-level leader of the religion, decided to make a branch called Incheondo () in 1923. This led to Woo taking the remaining sect of the Baekdogyo and relaunching the religion as Baekbaekgyo in 1923.

Beliefs and practices
