刘康 / Liu Kang, Dingtao King (Western Han)

Overview

刘康 / Liu Kang, Dingtao King, enters the wiki through Hanji 551 as 汉成帝’s brother and the father of the Dingtao king 刘欣 / 后来的汉哀帝. Hanji 484 and Hanji 498 show him first as Yuan’s favored son and alternative heir. Hanji 518 adds the Chengdi-era consequence: the childless emperor keeps Liu Kang close in the capital, but 王凤 uses an eclipse warning to send him back to his fief.

Current Profile

The current evidence is narrow but now spans two succession moments before Liu Xin. Hanji 484 shows Liu Kang as a favored son whose position already worries Kuang Heng because ruler intimacy can invite people to exploit consort and heir hierarchy. Hanji 498 then shows Liu Kang as a live alternative to Liu Ao in Yuan’s final illness. Yuan praises his talent partly through musical performance, feels attended by him and Fu Zhaoyi, and considers the Emperor Jing precedent for replacing an heir. Liu Kang’s candidacy fails not because the source proves him unfit, but because 史丹 / 施丹 makes replacing the long-established crown prince politically dangerous.

Hanji 551 then shows Liu Kang posthumously shaping the next succession. The host says Chengdi and Liu Kang had a good relationship and suggests that Chengdi’s earlier wish to use Liu Kang as a counterweight to Wang-family outer relatives may have ended with Liu Kang’s unclear death. That makes Liu Xin’s candidacy emotionally and politically legible: Chengdi can prefer his dead brother’s son while also avoiding the ritual awkwardness of making a brother into a son.

Hanji 518 supplies direct support for the closeness and counterweight field without resolving the later death claim. Chengdi, ill and without a son, keeps Liu Kang at court and openly treats his presence as succession reassurance. Wang Feng reads that proximity as dangerous, converts the eclipse into a demand that Liu Kang leave, and prevails despite the brothers’ tearful separation. Liu Kang therefore links two succession crises: he nearly displaces Liu Ao under Yuan, then becomes a possible Chengdi heir or counterweight whose court presence alarms the Wang-family power center.

Key Characteristics

• Western Han Dingtao king and father of Liu Xin, later Han Aidi.
• Yuan-era favored son and alternative heir candidate whose branch becomes a warning before it nearly displaces Liu Ao.
• Brother of Han Chengdi whose remembered closeness helps explain Chengdi’s affection for Liu Xin.
• Royal relative kept near the childless Chengdi as succession reassurance, then sent back to his fief after Wang Feng’s eclipse memorial.
• Source-scoped possible counterweight to Wang-family power before his death.
• Succession-background figure rather than a full biographical subject in the current wiki.

Evidence

• Father-son link: Hanji 551 identifies Liu Xin as Liu Kang’s son and Chengdi’s nephew.
• Earlier warning: Hanji 484 says Yuan favors Fu Zhaoyi and Liu Kang, making the crown-prince branch vulnerable enough for Kuang Heng to warn about嫡庶 order.
• Alternative-heir pressure: Hanji 498 says Yuan considers replacing Liu Ao with Liu Kang.
• Bedside and favor field: Hanji 498 links Liu Kang’s appeal to talent, musical performance, Fu Zhaoyi’s favor, and attendance during Yuan’s illness.
• Chengdi affection: Hanji 551 says Chengdi’s affection for Liu Kang helps explain preference for Liu Xin.
• Capital presence and departure: Hanji 518 says Chengdi keeps Liu Kang close because he has no son, but accepts Wang Feng’s eclipse-based demand that Liu Kang return to his fief.
• Suspicious-death interpretation: Hanji 551 presents Liu Kang’s death and Wang-family connection as interpretive background rather than settled proof.

Qualifications

This page is intentionally narrow. Hanji 484 and Hanji 498 do not settle Liu Kang’s title chronology, full talents, or whether he would have governed better than Liu Ao. Hanji 518 does not establish that Wang Feng’s eclipse interpretation was sincere, that Liu Kang was formally designated as Chengdi’s heir, or every detail of the departure. Hanji 551 does not provide Liu Kang’s full life, death record, mother, household, or exact political role. The claim that Chengdi felt guilt or used Liu Kang against the Wang side remains episode interpretation.

What Changed

• Added Hanji 518’s Chengdi-era capital presence, succession-reassurance role, eclipse-based removal, and tearful departure.
• Connected Liu Kang’s Yuan-era alternative-heir status to his later value and danger as a possible counterweight under Chengdi.

Relationships

• 汉成帝 - brother whose heir preference is partly explained through Liu Kang.
• 汉元帝 - father who considers favoring Liu Kang over Liu Ao late in life.
• 傅昭仪 - favored consort whose proximity strengthens Liu Kang’s appeal.
• 临终废储阻断 - concept explaining why Liu Kang’s alternative-heir moment fails.
• 汉哀帝 - son whose Dingtao-line candidacy benefits from Chengdi’s affection for Liu Kang.
• 中山王刘兴 - brother-line alternative whom Chengdi does not choose.
• 王根 - Wang-family powerholder in the broader succession environment discussed by the source.
• 王凤 - outer-relative powerholder whose eclipse memorial forces Liu Kang away from Chengdi’s court.
