In Korean mythology, Dangun was the grandson of the gods, and the founder of Gojoseon, who set up the capital at Asadal. Legends say that around 4,340 years ago, "Joseon" was the name of the country that became Korea. So Dangun is believed to be an ancestor of the Korean nation. There was also a kingdom called "Joseon" later in Korean history, so Dangun's kingdom is called "Go" (meaning "Ancient") Joseon.
