芈八子 / 宣太后 / Xuan Taihou
芈八子 / 宣太后 / Xuan Taihou appears in 《资治通鉴·周纪》58丨赵武灵王如何打造强国 as the mother of Ying Ji, the future 秦昭襄王. The episode names her briefly while explaining how Qin handles the succession after 秦武王 dies without a son.
《资治通鉴·周纪》59丨一朝君王一朝臣 keeps her in that same threshold role while adding 魏冉. The episode says Wei Ran uses hard measures to make his nephew Ying Ji succeed after Qin Wuwang’s brothers fight for the throne, tying Xuan Taihou’s branch to Qin’s first post-Wuwang power struggle.
《资治通鉴·周纪》60丨 中国第一位把持朝政的太后竟是她？ turns that threshold into the central story. Because 秦昭襄王 is young, Xuan Taihou holds court power, hands major authority to Wei Ran, promotes her kin and the ruler’s brothers, and shapes early Qin policy through 太后摄政 and 楚系外戚政治. The episode also makes her diplomatic effect concrete: she arranges a Chu bride for Qin Zhaoxiang Wang, warms 秦国-楚国 relations, and helps move Qin away from Han and Wei until the 芈横 hostage incident breaks the alignment.
《资治通鉴·周纪》62丨稷儿，诓你舅舅的“腿”啊 uses Xuan Taihou indirectly as the kinship premise behind 楚怀王’s fatal confidence. Chu Huaiwang believes 秦昭襄王, as Xuan Taihou’s son and therefore his nephew, is unlikely to trap him. The source turns that assumption into a limit case for 楚系外戚政治: maternal Chu ties can shape Qin diplomacy, but they do not prevent Qin from detaining the Chu king when state advantage is available.
《资治通鉴·周纪》85｜宣太后为何私通30年后暗杀了老情人？ returns to Xuan Taihou as a direct actor on Qin’s northern frontier. The episode says she maintained a roughly thirty-year relationship with the 义渠 king and had two sons by him, while Yiqu did not raid Qin’s rear during Qin’s major campaigns. Because the sources cannot prove motive, the page records the strategic effect without claiming certainty about affection versus calculation. When Qin’s timing matures, Xuan Taihou lures the Yiqu king to 甘泉宫, kills him, and lets 秦国 destroy Yiqu and create 北地郡, making her the source case for 亲密关系式边患安抚.
《资治通鉴·周纪》88丨你怎么看待凤凰男（2） uses Xuan Taihou as one half of Fan Ju’s blunt diagnosis of Qin court power. Fan Ju’s statement that Qin has no king, only the queen mother and 穰侯魏冉, does not add a new frontier action by Xuan Taihou; it marks the point where her regency-era authority has become a problem 秦昭襄王 must address if he wants Fan Ju’s 远交近攻 to be implemented.
《资治通鉴·周纪》89丨秦王竟被他怼“妈宝男”？ places Xuan Taihou above the four named Qin nobles. The episode does not add another action like the Yiqu killing; it shows that her earlier 太后摄政 has left a durable court order in which 魏冉, 华阳君, 泾阳君, and 高陵君 can make Qin Zhaoxiang Wang politically dependent despite his ruler title.
《资治通鉴·周纪》90丨揭秘先秦最完美的复仇 adds the qualification to that court-power story. The episode says 秦昭襄王 does recover practical authority, but it also cautions that Xuan Taihou may not have been literally deposed in every source tradition. The wiki therefore treats this as a reduction or displacement of queen-mother dominance, not as a certain clean break.
《资治通鉴·周纪》91丨触龙如何敲开守寡赵太后的门（1） uses Xuan Taihou’s death as the transition marker into 265 BCE. Her disappearance from Qin politics and 魏冉’s removal make room for 秦昭襄王 to set 安国君柱 as crown prince while the narrative turns to another queen-mother figure, 赵威后, in Zhao.
