卫氏朝鲜 / Wiman Joseon

Overview

卫氏朝鲜 / Wiman Joseon is the polity founded by 卫满 after migration from Yan. Its Han-recognized frontier role, regional expansion, later control of neighboring rulers’ court access, envoy violence, retaliation, battlefield resistance, and final conquest form one long arc from delegated intermediation to imperial war.

Current Profile

Hanji 364-2 supplies the polity’s origin and the institutional dispute before the war. Wiman crosses the Pei River with refugees and followers, establishes himself at 王险城, and receives recognition as a Han outer vassal expected to defend the frontier without blocking nearby rulers from the imperial court. His later expansion gives the dynasty inherited by 卫右渠 greater regional weight. Under Ugeo, the episode says that direct court access is obstructed, and Han pressure to reopen it fails.

Hanji 366-1 then supplies the war’s opening sequence. After 涉何 kills a Joseon escort officer and receives a Liaodong appointment, Joseon retaliates and kills him. Joseon defeats Yang Pu’s first force, holds Xun Zhi at the Pei River, and then approaches submission under renewed pressure. That off-ramp fails when the crown prince refuses a Han demand that his armed following disarm.

At Wangxian City, Wiman Joseon exploits or is protected by the split between Xun Zhi and Yang Pu, preferring Yang Pu’s surrender channel while resisting Xun Zhi. Hanji 366-2 shows that after Yang Pu’s arrest creates unified Han command, senior officials defect, Ugeo is killed, and remaining resistance under Seong Gi is overcome through persuasion from Ugeo’s son and the son of a defector. Han then converts the conquered space into the 汉四郡.

Key Characteristics

• Regional polity represented across immediate escalation, resistance, failed submission, siege, and conquest.
• Refugee-founded polity whose authority grows through Han recognition, coalition building, and regional expansion.
• Frontier intermediary expected to preserve neighboring rulers’ direct access to the Han court.
• Actor in a retaliation cycle after a Han envoy kills one of its escort officers.
• Defender whose ruler offers submission but whose crown prince withdraws under reciprocal fear.
• Defender able to navigate competing Han military and diplomatic channels.
• Court whose senior officials divide when unified Han pressure increases.

Evidence

• Formation and recognition: Hanji 364-2 connects Wiman’s refugee coalition, Wangxian kingship, and outer-vassal agreement to the polity’s early expansion.
• Access dispute: Hanji 364-2 says Ugeo blocks neighboring states from direct access to the Han court and rejects She He’s demand.
• Escalation and early resistance: Hanji 366-1 connects envoy violence and retaliation to the war, then records defeat of Yang Pu and defense of the Pei River.
• Failed settlement: Hanji 366-1 says Ugeo offers submission but the crown prince turns back when ordered to disarm.
• Divided siege: Hanji 366-2 says Joseon prefers surrender to Yang Pu and resists Xun Zhi while the Han commanders remain divided.
• Elite fracture: Hanji 366-2 says senior officials defect and Sam arranges Ugeo’s death after the combined Han army increases pressure.
• Final settlement and reorganization: Hanji 366-2 says remaining resistance is removed and four commanderies are established.

Qualifications

This page does not adopt Hanji 366-2’s broad claim that the region was already Yan territory in the Spring and Autumn period. Hanji 364-2 adds an origin narrative but remains insufficient to settle the polity’s boundaries, population, political offices, the legal meaning of outer-vassal status, or the exact geography of the Pei River and Wangxian City. Hanji 366-1’s 106 BCE date and detailed submission terms remain source-scoped, while Hanji 366-2’s closing Jizi passage is moral historiography rather than a direct description of this final regime.

What Changed

• Extended the profile backward to Wiman’s refugee coalition, Han recognition, regional expansion, and the inherited obligation to preserve neighboring rulers’ court access.
• Reframed the She He incident as the violent end of an older access-and-hierarchy dispute rather than an isolated border clash.

Relationships

• 卫右渠 - final king killed during the regime’s collapse.
• 王险城 - capital and final siege center in the episode.
• 荀彘 - Han land commander who completes the intensified assault.
• 杨仆 - Han commander whose separate surrender channel Joseon initially prefers.
• 汉四郡 - successor administrative structure imposed after conquest.
• 涉何 - envoy whose violent mission and death precede the invasion.
• 卫山 - envoy whose surrender agreement fails at the crossing stage.
• 卫满 - founder whose recognition agreement establishes the polity’s early frontier role.
• 朝见通道垄断 - mechanism by which Ugeo’s obstruction challenges the inherited agreement.
