Who is Dangun? Guide to the Founder of Korea
Dangun is the mythological founder of Korea. He is the grandson of Hwanin, the ruler of heaven, and the son of Hwanung, the heavenly prince who descended to a mountain in what is now northern Korea. His mother was a bear who prayed to become human and, after enduring a hundred days in a cave eating only garlic and mugwort, was transformed into a woman named Ungnyeo. Dangun founded the first Korean kingdom, Gojoseon, in 2333 BCE - a date so central to Korean identity that it is still used in the Korean calendar. He is preserved as the shared ancestor of the Korean people, and his legend is the founding narrative of Korean national identity.

Definition - Dangun
The mythological founder of the first Korean kingdom, Gojoseon, traditionally dated to 2333 BCE. Dangun is the grandson of the heavenly ruler Hwanin and the son of the heavenly prince Hwanung and the bear-turned-woman Ungnyeo. His full title is Dangun Wanggeom. He is preserved in the Samguk Yusa and is the shared ancestor of the Korean people in national tradition.
His full title, Dangun Wanggeom, combines two elements: Dangun, possibly meaning “altar prince” or “shaman-king,” and Wanggeom, which may be a personal or throne-name. The name reflects his dual role - as a divinely descended figure connected to sacred altars, and as an earthly ruler establishing a kingdom.
The Dangun story is preserved most fully in the Samguk Yusa, a thirteenth-century collection of Korean legends and historical materials compiled by the Buddhist monk Iryeon in 1281 CE. Iryeon drew on much older oral traditions and lost written sources. The Dangun narrative may be considerably older than its written attestation, though its exact age is debated.
Hwanung descends to earth
The story begins in heaven. Hwanin, the ruler of the heavenly realm, had a son named Hwanung who looked down at the world of men and desired to help them. Hwanin gave his son permission to descend and rule a portion of the earth. He gave him three heavenly treasures and three thousand followers.
Hwanung descended to the peak of Mount Taebaek (identified variously with the Baekdu-san mountain on the modern Korea-China border, or with other peaks). He set up a new state called Sinsi, “the divine city,” under a sacred tree. He was accompanied by three ministers: the Master of Wind, the Master of Rain, and the Master of Clouds. Together with his followers, he taught humanity 360 areas of knowledge - agriculture, medicine, laws, arts, moral distinctions between good and evil. Read Hwanung descending from heaven.
Under Hwanung’s rule, the region prospered.
The tiger and the bear
A tiger and a bear came to Hwanung and asked to become human beings. They wanted to live in the divine city as humans do.
Hwanung set them a test. He gave them twenty pieces of garlic and a bundle of mugwort (or, in some versions, sacred herbs of the mountain). He told them to enter a cave and eat nothing but these for one hundred days. If they endured, they would become human.
The tiger and the bear entered the cave. The tiger, restless and unable to bear the diet or the darkness, left the cave and returned to the wild. The bear endured. After twenty-one days (in some tellings; a hundred in others), she emerged from the cave transformed into a woman. She was called Ungnyeo, “Bear Woman.” Read Bear Woman Ungnyeo.
Ungnyeo, now human, longed for a child. She prayed to Hwanung under the sacred tree. Hwanung, moved, temporarily transformed himself into a mortal man and married her. She conceived and bore a son. That son was Dangun.
The founding of Gojoseon
Dangun grew up under his father’s rule at Sinsi. When he came of age, he moved south and founded his own kingdom, called Joseon (later called Gojoseon, “Old Joseon,” to distinguish it from the later Joseon Dynasty that took the same name). Traditionally, this founding is dated to 2333 BCE.
Dangun ruled for a very long time - the tradition preserves figures ranging from 1,500 years to over 1,900. During his reign, the Korean state was established, agriculture and the arts flourished, and the Korean people were formed as a distinct nation. At the end of his reign, he became a mountain god (sanshin), and his rule passed to successors.
The extremely long reign is a common feature of founder-mythologies; it collapses many generations of ruler-figures into a single archetypal founder. Historians and scholars generally read Dangun as representing the earliest layer of Korean political organisation rather than as a single historical individual.
Dangun in modern Korea
Dangun is a unifying symbol across both North and South Korea, though the two states interpret his legacy differently.
In South Korea, October 3 is celebrated as Gaecheonjeol (“Opening of Heaven Day”), a national holiday marking Dangun’s founding of Korea. Traditional Korean calendars sometimes use Dangi years, counted from 2333 BCE. The year 2026 CE is Dangi 4359.
In North Korea, Dangun’s tomb was reportedly discovered near Pyongyang in 1993, and the state built a large mausoleum on the site. The tomb’s authenticity is disputed by scholars outside North Korea, but the North Korean government treats it as historical.
The Dangun tradition is a matter of contemporary religious and cultural practice. Some new religious movements in Korea (including Daejongism, founded in 1909) treat Dangun as an object of active worship. The mainstream Korean public understands him more as a national ancestor and cultural symbol than as a religious figure, but the reverence remains real.
Dangun compared to other founder-figures
Dangun belongs to a category of divinely-descended national founders.
| Tradition | Founder | Origin | Notes |
|---|---|---|---|
| Korean | Dangun | Son of heavenly prince and bear-woman | Founded Gojoseon; national ancestor |
| Japanese | Jimmu | Descendant of Amaterasu | Traditional first emperor |
| Roman | Romulus | Son of Mars and Vestal Virgin | Founded Rome |
| Chinese | Yellow Emperor | Legendary ruler | Cultural ancestor |
| Vietnamese | Lac Long Quan and Au Co | Dragon-lord and mountain fairy | Ancestors of Vietnamese people |
| Ethiopian | Menelik I | Son of Solomon and Sheba | Founded Solomonic dynasty |
The pattern - a divinely-descended founder whose story explains a people’s origin - is common across East Asia and beyond. What is distinctive about Dangun is the specific bear-mother motif, which reflects an older layer of Northeast Asian shamanic religion in which certain animals were considered ancestral or spiritually significant.
Read the stories
Dangun and his family appear in several Korean stories on the site:
- Hwanung Descending from Heaven
- Bear Woman Ungnyeo
- Dangun Founding Korea
- Jumong Foundation Myth
- Mountain Spirit Sanshin
- Yongwang the Dragon King
- The Sun and Moon Siblings
Dangun is what the Korean tradition kept as its foundational story - the meeting point of heaven, earth, and the animal world, and the origin of a people. His mother’s endurance in the cave, his father’s descent from heaven, and his own founding of the first Korean kingdom together form a national ancestry that continues to be honoured every October third. He is not a distant figure. He is the ancestor Korea, in its own tradition, traces itself back to.
Frequently Asked Questions
Who is Dangun?
Dangun is the mythological founder of the first Korean kingdom, Gojoseon, traditionally dated to 2333 BCE. He is the grandson of the heavenly ruler Hwanin, the son of the heavenly prince Hwanung, and the son of Ungnyeo, a bear who became human through prayer and endurance. He is considered the shared ancestor of the Korean people.
Who was Dangun’s mother?
Ungnyeo, “Bear Woman.” She was originally a bear who prayed to become human and, together with a tiger, was set a test by Hwanung: to remain in a cave for a long period eating only garlic and mugwort. The tiger left the cave and returned to the wild. The bear endured and was transformed into a woman. She married Hwanung and bore Dangun.
When did Dangun found Korea?
According to tradition, 2333 BCE. This date is preserved in the Samguk Yusa and is used in the traditional Korean Dangi calendar, which counts years from Dangun’s founding. October 3 is celebrated in South Korea as Gaecheonjeol (“Opening of Heaven Day”), commemorating the founding.
Is Dangun a real historical figure?
Almost certainly not as described. The extremely long reign (over 1,500 years in some accounts) is a common feature of founder-mythologies, where multiple generations of early rulers are collapsed into a single archetypal figure. Historians generally read Dangun as representing the earliest layer of Korean political organisation, not as a single individual. However, he is a real object of cultural reverence and, for some Koreans, religious worship.
What is Gojoseon?
Gojoseon (literally “Old Joseon”) is the name of the first Korean kingdom, said to have been founded by Dangun. The “old” prefix distinguishes it from the later Joseon Dynasty (1392-1897 CE), which took the same name. Gojoseon existed in what is now northern Korea and parts of northeastern China; its exact borders and duration are matters of historical debate.
Is Dangun worshipped today?
Some contemporary Korean religious movements treat Dangun as an object of active worship. Daejongism, founded in 1909, is centred on Dangun devotion. Most Koreans, however, understand Dangun more as a national ancestor and cultural symbol than as a religious figure - the reverence is genuine but is expressed through civic rather than devotional channels.
