History & Origin
The Dangun Myth: According to Korean mythology, Hwanung, the son of the Lord of Heaven (Hwanin), descended to Mount Baekdu with 3,000 followers and established the City of God (신시). A bear and tiger wished to become human and were given the challenge of staying in a cave for 100 days eating only garlic and mugwort. The tiger gave up, but the bear persevered and transformed into a woman (Ungnyeo). Hwanung married Ungnyeo, and their son Dangun founded the first Korean kingdom of Gojoseon.
