过继宗法礼制政治 / Adoptive Lineage Ritual Politics

Definition

过继宗法礼制政治 / Adoptive lineage ritual politics is the pattern where adoption, collateral succession, heir identity, and ancestral-sacrifice obligation are interpreted as public political doctrine rather than private family custom.

Current Synthesis

The current evidence now has a before-and-after shape around 汉哀帝. Hanji 555 supplies the pre-accession branch: after 汉成帝 makes the Dingtao king his son and heir, 严从 argues that Liu Xin should not thank Chengdi for preserving the Dingtao birth-father line. Once the heir belongs to Chengdi’s line, even grateful speech about birth-family benefit can look like incomplete conversion.

Hanji 575 shows 施丹 using the doctrine after accession to restrain Aidi himself: because Aidi has inherited Chengdi’s line and ancestral temple, Shi Dan argues that Aidi cannot separately elevate the Dingtao birth-parent line with officials, vehicles, garments, and a capital temple as if there were two supreme centers.

Hanji 618 gives the later coercive version, where 王莽 uses adoptive-heir doctrine to manage the political fallout from killing most of 汉平帝’s Wei birth relatives. By having Zongbo Feng lecture the court on “嗣子大义,” Wang Mang makes Pingdi’s status as Aidi’s heir a reason to subordinate birth-family attachment to dynastic-ritual duty.

The Jin-family succession dispute makes the mechanism concrete. Jin Dang and Jin Qing hold inherited status through collateral lines, so Wang Mang can use their case as an analogy for Pingdi. Jin Qing’s suggestion that Jin Dang should personally sacrifice to his birth father and grandfather undermines the analogy by restoring birth-lineage obligation inside an adoptive succession frame. Zhen Han’s accusation and reward show how quickly an interpretive disagreement can become political offense when lineage doctrine protects a purge.

Key Claims

• Adoption and heir installation can preserve property, status, and ancestral sacrifice while redefining public kinship obligation, even before accession through speech, thanks, and visible birth-family attachment.
• The same doctrine can restrain a reigning emperor’s birth-parent honors as well as later restrain a child emperor’s birth-family claims.
• When a child ruler is installed as another emperor’s heir, adoptive duty can be used to weaken claims from the ruler’s birth family.
• Court lectures on ritual can operate as political discipline when officials are made to hear and accept a sanctioned interpretation together.
• Collateral title succession cases can be turned into analogies for imperial succession and court loyalty.
• Reasserting birth-lineage sacrifice inside an adoptive frame can threaten the political legitimacy of a purge.
• Punishment and reward around ritual interpretation teach other officeholders which family reading is safe to perform.

Evidence

• Pre-accession thank-you test: Hanji 555 says Liu Xin wants to thank Chengdi after Liu Jing is made Dingtao king to preserve the birth-father line.
• Status-conversion warning: Hanji 555 says Yan Cong warns that Liu Xin has become Chengdi’s son and should not still act from birth-kin attachment.
• Punished contrary advice: Hanji 555 says Zhao Xuan advises thanks, Liu Xin follows him, Chengdi becomes angry, and Zhao Xuan is demoted.
• Aidi succession constraint: Hanji 575 says Shi Dan argues that Aidi’s succession into Chengdi’s line prevents him from treating the Dingtao parental line as a parallel supreme center.
• Temple boundary: Hanji 575 says Shi Dan opposes Aidi personally sacrificing to Dingtao Gonghuang or building a capital temple for him because the adoptive imperial line fixes the main ritual obligation.
• Institutional background: Hanji 618 explains over-adoption as a way for sonless households to continue inheritance, identity, and sacrifice.
• Pingdi analogy: Hanji 618 says Wang Mang frames Pingdi as Aidi’s heir and therefore as someone who should not prioritize Wei birth-family feeling.
• Public ritual instruction: Hanji 618 says the lecture is given before high officials, generals, palace attendants, and civil and military officers.
• Collateral succession model: Hanji 618 says Wang Mang brings Jin-family heirs into the lecture because their inherited titles resemble the adoptive/collateral logic being imposed on Pingdi.
• Birth-lineage counter-reading: Hanji 618 says Jin Qing argues for sacrifices to Jin Dang’s birth father and grandfather, contradicting Wang Mang’s intended lesson.
• Punishment and reward: Hanji 618 says Zhen Han accuses Jin Qing of grave offenses, Jin Qing dies in prison, and Wang Mang rewards Zhen Han.
• Learned performance: Hanji 618 says Jin Tang does not return home on the day he receives the marquisate, performing the sanctioned great-lineage posture.

Counterevidence & Qualifications

The concept still rests on short Western Han episode notes and should not be generalized to all adoption or lineage practice without more evidence. Hanji 555 shows how the doctrine is read around Liu Xin’s thanks and Fu/Ding access, but it does not settle the full law of adoption, the full text of Liu Xin’s memorial, or Chengdi’s private intent. Hanji 575 shows principled ritual resistance to Aidi’s birth-parent honors but does not settle every legal detail of Dingtao titles or temple practice. Hanji 618 shows how Wang Mang weaponizes one doctrine in one court crisis; it does not prove that every adoptive succession had the same political meaning. Zongbo Feng, Zhen Han, the Jin-family genealogy, exact ritual wording, and Wang Mang’s inner motives remain source-scoped.

What Changed

• Added Hanji 555’s pre-accession Liu Xin branch, where a thank-you memorial exposes whether the adopted heir still treats birth-family benefit as his own.
• Preserved Hanji 575’s Aidi/Chengdi/Dingtao branch, where adoptive-lineage doctrine restrains birth-parent honor.
• Preserved Hanji 618’s later Wang Mang/Pingdi branch as the coercive and punitive version of the same doctrine.
• Refined the concept so it covers both ritual boundary maintenance and weaponized purge justification.
