Cheondogyo (천도교 / 天道教), usually anglicized as Cheondoism, is a Korean religion founded in 1905, based on the 19th Century Donghak (Eastern Learning) Neo-Confucian movement, but incorporates elements of Buddhism, Taoism and Korean Shamanism. It had 1.13 million followers in South Korea as of 2005, and 2.8 million in North Korea as of 2000.
The Cheondoist flag (in South Korea at least), known as the Geungulgi (궁을기 / 弓乙旗), is a white-red vertical bicolor, featuring the Cheondoist emblem, known as the Geunguljang (궁을장 / 弓乙章), counterchanged. The dot at the centre represents the human mind (마음, literally 'heart'); the two crescents represent the human body (몸); and the ring represents the human character (성품).
