Ancient Choson Rulers

Annals of the Danguns are recorded in Gyuwon Sahwa and Hwandan Gogi. Gyuwon Sahwa is a credible historical record written in 1675, which is based on earlier records that are now lost. Hwandan Gogi is considered as a blasphemy, which describes Korean history back to 8th millennium BC, but part of it is based on Gyuwon Sahwa and other records.
