Old Chosŏn

Lore & Background

Old Chosŏn's founding is attributed to the legendary king Tan'gun, who according to the Samguk yusa was born from the heavenly prince Hwanung and a bear-woman, Ungnyeo, and established the kingdom in 2333 BCE. While Tan'gun is a mythological figure, some interpret his legend as a reflection of the sociocultural conditions of the kingdom's early development. Chinese sources such as the Shangshu dazhuan and the Book of Documents claim that in the 12th century BCE, Jizi (Kija), a sage from the Shang dynasty royal family, immigrated to the northern part of the Korean Peninsula and became the founder of Kija Chosŏn, though there are debates regarding Kija Chosŏn's existence. In 194 BCE, the ruling dynasty of Old Chosŏn was overthrown by Wi Man, a refugee from the Han vassal state of Yan, who established Wiman Joseon. In 108 BCE, the Han dynasty under Emperor Wu invaded and conquered Wiman Joseon, establishing four commanderies. After the fragmentation of the Han Empire during the 3rd century and the subsequent chaotic 4th century, the area escaped Chinese control, and Goguryeo conquered the Lelang commandery in 313 CE — though by then the territory of Old Chosŏn had been under Chinese commanderies for centuries. The capital of Old Chosŏn was Wanggeom-seong (now Pyongyang), but clear evidence for it being the capital exists only from the Wiman Joseon period (after 194 BCE).

Old Chosŏn holds a foundational place in Korean history and identity. Its mythological founding by Tan'gun is officially celebrated as Gaecheonjeol ('National Foundation Day') in both North and South Korea, and the account of Tan'gun has played an important role in the development of Korean identity. The kingdom possessed the most advanced culture in the Korean Peninsula at the time and marked a progression towards more centralized states. The three main founding myths—centered on Tan'gun, Kija, and Wi Man—reflect different layers of historical and cultural influence, including native Korean traditions, Chinese textual traditions, and interactions with neighboring states. Academic perspectives vary widely: some view the Tan'gun myth as a native product of proto-Koreans, while others suggest Chinese origins; the Kija myth is often dismissed as a later Chinese fabrication or conflation, and Wi Man is generally accepted as a historical figure. The debates surrounding Old Chosŏn's early chronology and the existence of Kija Chosŏn highlight the challenges of reconstructing ancient history from mythological and fragmentary sources. Ultimately, Old Chosŏn remains a key symbol of Korean antiquity and a subject of ongoing scholarly discussion.

The Question of Who King Chun Was

King Chun occupies a peculiar position in Korean historiography, one defined less by confirmed biography than by the absence of it. Native Korean records contain no trace whatsoever of a ruler bearing the name "Chun" who governed Old Chosŏn, leaving his very identity in a state of perpetual scholarly dispute. The figure emerges almost exclusively from Chinese sources, most notably the Book of the Later Han, which identifies him as the final sovereign of Kija Chosŏn—a dynasty supposedly established by the legendary figure Kija (Jizi) as a second ruling house within the broader Old Chosŏn framework. In some interpretive scenarios, Chun is treated simply as the last king of Old Chosŏn itself, while in others he is specifically the terminal monarch of this Kija-founded branch. This ambiguity means that any discussion of his reign, his policies, or his personal life is necessarily speculative, resting on a single foreign textual tradition rather than on indigenous Korean documentation. The result is a king who exists primarily as a narrative placeholder between the mythic founding era and the historically more secure period of Wiman's rule.

The Refugee Who Became a Usurper

The most dramatic episode in Old Chosŏn's later history is the arrival and eventual betrayal of Wi Man. According to the 3rd-century Chinese text Weilüe of the Sanguozhi, Wi Man was a military officer of the Yan of northeastern China who fled to the northern Korean peninsula in 195 BCE from the encroaching Han dynasty. He submitted himself to King Jun's authority, and the king granted Wi Man's request to take up a military post as commander of the western borders. This placement gave Wi Man both a legitimate position within the state's power structure and direct access to armed forces stationed at a strategic frontier. The arrangement, however, proved fatal. Wi Man subsequently raised a revolt against King Jun, overthrowing the established dynasty and seizing the throne for himself in 194 BCE. His successful usurpation marked the founding of an entirely new ruling house, Wiman Joseon, which would go on to dominate the region until its conquest by the Han dynasty in 108 BCE.

Flight South and the Mahan Legend

According to the mythic tradition, this southern migration led to the founding of the Mahan confederacy, with Chun installed as its first sovereign. Yet the textual evidence for this claim is far thinner than the narrative suggests. The Book of the Later Han, the original source for the story, never explicitly names Mahan. Instead, it refers to Chun as the "King of Han" (韓王), a designation that could apply to any of several polities in the region. The specific identification with Mahan was a later scholarly inference, built largely on the logic of geographical proximity—assuming that a king fleeing northward power would naturally settle in the south. This means the entire legend of Chun as Mahan's founding king rests on an interpretive leap rather than a clear textual statement, making it one of the most contested and least secure episodes in early Korean political history.

The Sinicization Debate and Modern Rejection

Contemporary historians have largely rejected the entire Kija Chosŏn narrative. Their central argument is one of sinicization: they contend that Chinese textual traditions projected foreign dynastic frameworks onto Korean history. By denying the historical existence of Kija (Jizi) and the dynasty he supposedly founded, these scholars simultaneously dismantle the stories of his rule. What survives of the broader narrative is the more secure fact that Wiman Joseon did exist and that Wi Man did overthrow a preceding dynasty. From this, historians deduce that a king of the original Old Chosŏn line likely suffered a fate parallel to Chun's—deposed and possibly driven into southern exile—though the specific identity and details of that ruler remain firmly in the realm of speculation rather than established fact.
