《资治通鉴·周纪》76丨谁给了楚顷襄王的自信？

Summary

This 芮淇讲透资治通鉴 episode moves through 周赧王’s thirty-third and thirty-fourth years, 282-281 BCE, with 秦昭襄王 punishing 赵惠文王赵何 after Zhao refuses a joint attack on 齐国. It then turns to the odd report that 芈横 / 楚顷襄王 wants to join 齐国 and 韩国 against Qin while also plotting against the 周王室, a move the host treats as source-questionable because Mi Heng has recently been cautious and afraid of Qin. The strongest synthesis is that late Zhou weakness does not erase symbolic cost: 东周武公 persuades Chu that attacking a tiny royal domain for 九鼎 would bring little material gain but severe legitimacy danger.

Key Claims

• In 282 BCE, 秦昭襄王 attacks 赵国 after 赵惠文王赵何 refuses Qin’s proposal for a joint campaign against 齐国.
• The episode reads the attack through post-coalition spoils imbalance after 乐毅 and the anti-Qi coalition: Qin spent effort, received less than it wanted, and stayed dissatisfied.
• The host treats the refusal to attack Qi and the recent 完璧归赵 humiliation as possible paired causes for Qin’s punitive move against Zhao.
• In 281 BCE, Qin again attacks Zhao and takes 石城, located in the episode near modern southwest Shijiazhuang.
• The same year, Qin appoints 魏冉 as chancellor again, continuing the Qin court sequence around 秦昭襄王.
• The source says 楚国 wants to join Qi and Han in attacking Qin while also considering an attack on the Zhou royal domain.
• The host questions the plausibility of 楚顷襄王 suddenly becoming aggressive toward Qin and Zhou after earlier fear, marriage accommodation, and the trauma of 楚怀王’s death in Qin.
• 周赧王 sends 东周武公 to persuade Chu’s令尹昭子 that the royal house is not worth attacking.
• Dongzhou Wugong’s argument is material and symbolic: Zhou territory and people are too small to enrich or strengthen Chu, while attacking the nominal Son of Heaven would look like regicide.
• The 九鼎 are treated as a tempting object but also a trap: moving them to Chu could invite broader opposition against Chu.
• The episode uses the Zhou background to clarify the difference between Western Zhou as a dynasty period and the later 西周国 / 东周国 split inside the diminished royal domain.
• The closing preview says Qin later invites Zhao Huiwen Wang to meet at 渑池, which recalls the earlier Qin trap against Chu Huaiwang at 武关.

Key Quotes

“谁给了楚顷襄王的自信？” - the episode’s title question about the plausibility of Chu’s reported boldness.

“土地很小，总面积不过百里” - Dongzhou Wugong’s material framing of Zhou’s limited value.

“九鼎运到楚国时，天下伐楚的大军恐怕也会到来” - the episode’s summary of symbolic trophy risk.

Connections

• 秦昭襄王, 赵惠文王赵何, 秦国, 赵国, 石城, and 渑池 - Qin-Zhao pressure sequence and next diplomatic setup.
• 乐毅, 燕国, 齐国, 魏国, and 联军战后利益失衡 - post-anti-Qi background for Qin’s frustration.
• 蔺相如, 和氏璧, and 完璧归赵式外交 - possible emotional and diplomatic residue before Qin attacks Zhao.
• 芈横 / 楚顷襄王, 楚怀王, 楚国, 韩国, 合纵, and 战国同盟转向 - contested Chu anti-Qin move.
• 周赧王, 东周武公, 周王室, 九鼎, and 周王室象征威慑 - persuasion branch and symbolic-cost frame.
• 东周国, 西周国, 东周西周分裂, 周武王, 周幽王, 周平王, and 洛邑 - Zhou background and naming clarification.

Contradictions

• Source-critical tension, not a settled contradiction: earlier pages such as Zhouji 67 portray 楚顷襄王 as swallowing humiliation and renewing marriage diplomacy under Qin pressure. This episode’s report that Chu suddenly wants to attack Qin and menace Zhou is therefore kept as a questioned source claim rather than treated as stable character evidence.
• No direct contradiction found in the Qin-Zhao chronology. The source extends Zhouji 73 and Zhouji 74 by moving from post-Qi spoils and the He Shi Bi exchange to direct Qin attacks on Zhao and the coming Mianchi meeting.
