余善 / Yu Shan (Dongyue king)

Overview

余善 / Yu Shan is the Dongyue ruler whose killing of Han officials and self-proclamation as “武帝” trigger a multi-route campaign ordered by 汉武帝, and whose rule ends through internal killing and surrender under Han pressure.

Current Profile

Hanji 356-1 introduces Yu Shan as the rebel target after the Nanyue campaign. It says he kills Han officials, assumes an imperial title, and draws a multi-route force that includes 楼船将军杨仆. That source ends at mobilization and does not establish his fate.

Hanji 356-2 supplies the outcome. Yu Shan is presented as cunning and already occupying difficult terrain, but external pressure opens an internal fracture: 吴阳 defects with followers, and 建成侯敖 joins 繇王居股 in killing Yu Shan before surrendering. His death is therefore synthesized as conquest through military pressure plus elite defection, not as proof that terrain or direct battle alone decided the campaign.

Key Characteristics

• Dongyue ruler in open rebellion against Western Han authority.
• Challenger who is said to kill Han officials and adopt the title “武帝.”
• Campaign target of a multi-route Han mobilization that includes Yang Pu.
• Ruler whose difficult terrain does not prevent internal defections under outside pressure.
• Killed by Dongyue insiders who then surrender to Han.

Evidence

• Rebellion and title claim: Hanji 356-1 says Yu Shan kills court officials, rebels, and calls himself Wudi.
• Campaign response: Hanji 356-1 places him against forces dispatched by Han Wudi from several routes.
• Yang Pu connection: Hanji 356-1 makes the Dongyue campaign Yang Pu’s opportunity to redeem alleged faults after Nanyue.
• Defensive position and fracture: Hanji 356-2 says Yu Shan holds difficult ground while defections develop inside Dongyue.
• Death and surrender: Hanji 356-2 attributes his killing to Ao and Jugu, who then bring their followers over to Han.

Qualifications

Both supplied transcripts corrupt the name, using “于善” or “洛于善”; this page preserves the established 余善 identity. The sources do not provide a full accession, family, or administrative biography. Hanji 356-2’s claim that he killed an elder brother and its descriptions of his cunning remain episode-attributed, while the exact battlefield chronology and the private motives of the defectors are not established.

What Changed

• Added the campaign outcome: internal defectors kill Yu Shan and surrender under Han pressure.
• Replaced the earlier open-ended endpoint with a qualified account of terrain, fracture, and death.
