惠文后 / Queen Huiwen of Qin
惠文后 / Queen Huiwen of Qin appears in 《资治通鉴·周纪》60丨 中国第一位把持朝政的太后竟是她？ as 秦昭襄王’s formal mother in the Qin succession purge after 秦武王 dies. The episode says 魏冉 secretly executes her after suppressing 嬴壮 and the associated rebellion.
The page should remain source-scoped. Her importance here is not a developed biography but the severity of the post-Wuwang purge: the new 芈八子 / 宣太后 and Wei Ran power configuration removes not only rebel princes but also a senior palace figure tied to the previous order.
