涉何 / She He (Western Han)

Overview

涉何 / She He is the Western Han envoy sent to challenge 卫右渠’s blockade of neighboring rulers’ court access. His killing of a Joseon escort officer and subsequent appointment in Liaodong form the immediate escalation point before war with 卫氏朝鲜.

Current Profile

Hanji 364-2 defines the demand: neighboring small states must not be prevented from petitioning or attending the Han court. She He fails to make Ugeo accept it, then kills the escort officer who accompanies him to the frontier and reports the act as a victory. 汉武帝 appoints him eastern commandant of Liaodong rather than punishing him. Hanji 366-1 continues the same chain through Joseon’s attack and She He’s death, after which Wudi orders the invasion. The sequence presents court-access conflict, envoy violence, court ratification, and retaliation as connected rather than as an isolated border incident.

Key Characteristics

• Han envoy sent to press Wiman Joseon to accept an imperial demand.
• Agent tasked with reopening neighboring rulers’ direct access to the Han court.
• Diplomatic agent who turns a failed mission into lethal frontier violence.
• Official rewarded with a Liaodong appointment after reporting the killing.
• Immediate target of Joseon’s retaliatory frontier attack.
• Escalation figure whose death becomes the stated trigger for Han invasion.

Evidence

• Mission purpose: Hanji 364-2 connects She He’s mission to Ugeo’s obstruction of neighboring states’ petitions and court attendance.
• Killing and appointment: Hanji 364-2 says She He kills the escort officer after the failed demand and receives the Liaodong post.
• Failed mission and killing: Hanji 366-1 says She He kills a Joseon escort officer after Ugeo rejects the Han demand.
• Appointment and retaliation: Hanji 366-1 says Wudi appoints him in Liaodong and Joseon subsequently kills him in a frontier attack.
• War trigger: Hanji 366-1 links news of She He’s death to the imperial invasion order.

Qualifications

This is a source-bounded profile of the immediate escalation sequence. The episodes do not supply the full imperial instruction, She He’s legal authority, the killed officer’s securely normalized identity, or an independent chronology. Their summaries write 涉和; this page uses the received form 涉何.

What Changed

• Added the blocked court-access dispute as the substantive purpose of She He’s mission.

Relationships

• 卫氏朝鲜 - polity against which She He’s mission and violence are directed.
• 卫右渠 - ruler who rejects the demand She He carries.
• 汉武帝 - ruler who appoints She He and orders war after his death.
• 卫山 - later envoy whose own mission shows a second failed diplomatic off-ramp.
• 军令同步失灵 - related concept because diplomatic action and coercive policy cease to produce a shared settlement path.
• 朝见通道垄断 - access-control dispute that prompts She He’s mission.
