Korea's founding legend: Dangun, son of a heavenly prince and a bear-turned-woman, founded Joseon in 2333 BC.
See it on the Korean History map →What happened
In the myth (단군 신화), Hwanung, son of the heavenly lord Hwanin, descends to Mount Taebaek. A bear and a tiger ask to become human; told to stay in a cave eating mugwort and garlic, the tiger quits, but the bear becomes a woman, Ungnyeo. Her son with Hwanung, Dangun Wanggeom, founds Joseon (later called Gojoseon) at Asadal. The date 2333 BC comes from 15th-century court reckoning, not ancient records.
Why it matters
It became a core symbol of Korean identity, especially under foreign pressure: Goryeo under the Mongols, nationalists under Japanese rule, and both Koreas today.
Think of it like
Like Rome's Romulus and Remus: a founding story with a precise traditional date that history cannot confirm.
How we know
First written down by the monk Iryeon in the Samguk yusa, about 1281, citing older lost books, and in Yi Seung-hyu's Jewang ungi (1287). No archaeology confirms it.
Still debated
Some read the bear and tiger as memories of animal-totem clans merging, but that is interpretation. North Korea's 1993 claim to have found Dangun's bones is widely doubted.

▸Dangun founding myth is the traditional origin of GojoseonLegend & tradition
The connection
Korean tradition holds that Dangun Wanggeom founded Joseon, later called Gojoseon, at Asadal in 2333 BC and ruled for 1,500 years. Historians treat the myth as later memory-making: Gojoseon was real, but Dangun appears in no contemporary record.
When and how
Set at Asadal, a site never firmly located, in 2333 BC; recorded by the monk Iryeon in the Samguk yusa, about 1281.
How sure are we?
Only the myth itself, written down some 3,600 years after its stated date; Chinese texts mention Joseon from about the 7th century BC but never Dangun.
Debates and open questions
Whether the myth preserves memory of a real ruling clan, or of a priest-king title ('Dangun'), is debated.
▸Samguk yusa (Memorabilia of the Three Kingdoms) is the earliest surviving record of Dangun founding mythWell documented
The connection
Iryeon opens the Samguk yusa with Gojoseon: Hwanung, son of the heavenly lord Hwanin, descends to Mount Taebaek; a bear that endures 21 days in a cave becomes a woman and bears Dangun, who founds Joseon. Iryeon cites a 'Book of Wei' and an 'Old Record' (Gogi), so the story predates him.
When and how
Written down around 1281 by the monk Iryeon; a verse version followed in Yi Seung-hyu's Jewang ungi of 1287.
How we know
No earlier text with the myth survives. The 'Book of Wei' he quotes is not found in Chinese histories of that name, and the Gogi is lost.
Debates and open questions
How old the myth really is, whether the bear reflects an early clan totem, and how the 2333 BC date, fixed only in Joseon's Dongguk tonggam (1485), arose.
▸Dangun founding myth is celebrated on National Foundation Day by Republic of Korea (South Korea)Well documented
The connection
South Korea marks October 3 as Gaecheonjeol, 'the day heaven opened', honoring Dangun's founding. The holiday grew from rites of the Daejonggyo religion and the exiled Provisional Government; the Republic made it official in 1949 and used a Dangun-era calendar until 1961.
When and how
South Korea, every October 3 since 1949; earlier observed by Daejonggyo from 1909 and by the Provisional Government in Shanghai.
How we know
South Korean holiday law and government records, including the 1948 law adopting the Dangun calendar and its later repeal.
Debates and open questions
Critics question celebrating a myth as history; supporters see a unifying cultural symbol. North Korea, which promotes Dangun as historical, also holds ceremonies.
