公孙操 / Gongsun Cao
公孙操 / Gongsun Cao appears in 《资治通鉴·周纪》85｜宣太后为何私通30年后暗杀了老情人？ as the 燕国 chief minister who kills 燕惠王 and installs 燕武成王. The episode links his coup to Yan Huiwang’s lost prestige after the Le Yi replacement and Tian Dan’s recovery of Qi.
The page is source-scoped because the episode does not develop his biography. His role is to make Yan’s weakness visible internally: failed command succession and lost occupation gains become a palace-level power break that other states can exploit.
