赵敬肃王刘彭祖 / Liu Pengzu, Zhao King (Western Han)

Overview

赵敬肃王刘彭祖 / Liu Pengzu, Zhao King is 汉武帝’s elder half-brother, king of Zhao, father of 赵太子刘丹, and a long-ruling prince portrayed as harsh and legally cunning. The current sources span his preemptive accusation against 主父偃, his later accusation against 张汤, his defense of Liu Dan, and the 淖姬 succession branch.

Current Profile

Hanji 284 adds the earliest current layer. After 刘定国 and 齐厉王 die following accusation or investigation by Zhufu Yan, Liu Pengzu fears that Zhao will be next. The episode says he attacks first by reporting that Zhufu Yan accepts large bribes and forced the Qi king’s death. Hanji 285 completes the immediate result: Zhufu Yan admits bribery but denies causing the death, 汉武帝 first considers release, and 公孙弘 supplies the argument preceding execution and clan punishment. This establishes a consequential preemptive report without settling every charge or proving fear was Liu Pengzu’s only motive.

Hanji 338-2 supplies a later accusation pattern. The episode says Zhang Tang’s salt-and-iron-related policy pressure damages the revenue base Zhao had derived from smelting and casting. Liu Pengzu then uses Zhang’s personal visit and foot massage for favored clerk 鲁谒居 to allege that the two share a hidden scheme. The evidence supports a politically consequential accusation and Liu Pengzu’s ability to weaponize visible intimacy; it does not establish that the massage itself proves criminal collusion or that fiscal loss was his only motive.

Hanji 382-1 presents Liu Pengzu as a royal father caught between a damaging heir and central authority. 江充, then Jiang Qi, enters his circle because Jiang’s sister marries Liu Dan. After Jiang accuses Liu Dan in Chang’an, Liu Pengzu calls him an unreliable fugitive and then offers to serve on the frontier to save his son. The episode says the plea changes the outcome from death to demotion.

Hanji 382-2 adds a later household and succession profile. Liu Pengzu is described as skilled at using Han law to trap officials, with successive Zhao-household officials rarely lasting long. Hanji 237 part 2 sharpens the local-governance effect: senior appointees reportedly cannot remain for two years, lesser cases end in punishment and greater cases in death, while Liu Pengzu’s night patrols make travelers avoid staying in Handan. After 刘建 dies, he obtains Nuo Ji and has 刘淖子 with her. When Liu Pengzu dies without a settled successor, Wudi rejects Liu Naozi as desire-heavy and establishes 武始侯刘昌 instead.

Key Characteristics

• Western Han Zhao king and elder half-brother of Han Wudi in the episodes’ family frame.
• Reports Zhufu Yan after reading the Yan and Qi royal deaths as a warning that Zhao may be targeted next.
• Reports Zhang Tang by treating unusually personal care for Lu Yezhu as evidence of concealed collusion.
• Father of Liu Dan and early patron-context figure for Jiang Chong/Jiang Qi.
• Offers frontier service as a plea to save Liu Dan from execution.
• Described as harsh, legally cunning, dangerous to officials serving in Zhao, and personally active in night patrols.
• Later obtains Nuo Ji, fathers Liu Naozi, and leaves an unsettled succession in which Liu Naozi is rejected and Liu Chang selected.

Evidence

Preemptive report against Zhufu Yan:

• Hanji 284 says Liu Pengzu fears becoming the next target after the Yan and Qi cases and accuses Zhufu Yan of bribery and forcing Liu Cichang’s death.
• Hanji 285 says Zhufu Yan admits bribery, denies responsibility for the death, and is executed only after additional court pressure.

Zhang Tang accusation:

• Hanji 338-2 links Liu Pengzu’s hostility to Zhao’s lost smelting-and-casting revenue and says he reports Zhang’s foot massage for Lu Yezhu as a sign of hidden wrongdoing.

Royal family and plea:

• Hanji 382-1 says Liu Pengzu is Wudi’s elder half-brother, Liu Dan’s father, and the Zhao-court context for Jiang Qi.
• Hanji 382-1 says he challenges Jiang’s credibility and offers frontier service, after which Wudi spares Liu Dan’s life.

Governing style and later household:

• Hanji 382-2 describes Liu Pengzu as harsh and legally cunning, then says he obtains Nuo Ji and fathers Liu Naozi.
• Hanji 237 part 2 repeats the sub-two-year official tenure pattern and adds night patrols and traveler avoidance in Handan.

Succession endpoint:

• Hanji 382-2 says Liu Pengzu dies before the Zhao successor is fixed, leading Wudi to reject Liu Naozi and choose Liu Chang.

Qualifications

This page is bounded to six compact episodes. It does not reconstruct Liu Pengzu’s full reign, complete family, exact legal language, the full records of officials harmed in Zhao, or the legal procedure for succession. Hanji 284’s fear-and-preemption motive and Hanji 338-2’s fiscal motive remain source-scoped; neither proves that Liu Pengzu lacked other grievances or that every accusation was true. Hanji 285 confirms the report’s political consequence in the episode sequence but does not independently validate the wrongful-death charge or show that Liu Pengzu controlled the final decision. The exact official tenures, punishments, patrol force, crime-control effect, and traveler response in Hanji 237 part 2 remain episode-attributed.

What Changed

• Completed the immediate aftermath of Liu Pengzu’s report through Zhufu Yan’s trial, renewed court pressure, and execution.
• Kept the accusation’s political effect distinct from proof of every charge or control over the final decision.
• Added the local-governance consequence of official turnover and coercive night patrols without treating them as a general survey of Zhao administration.
