晋国 / Jin State
晋国 / Jin State appears in 《资治通鉴·周纪》06丨魏文侯选谁当宰相呢（2） through the comparison case of 晋幽公, whose death the episode reads through 《竹书纪年》. The state is also relevant to the source’s explanation of “秦晋之好,” the marriage-alliance idiom tied to 秦国 and Jin.
This page is source-scoped and does not duplicate the existing 晋文公 page; it provides a polity node for Jin-related ruler and marriage-alliance references.
《资治通鉴·周纪》07丨两起刺杀（1） adds Jin as the refuge destination for 王子定 and as a pole in 郑国’s alliance problem. The source says Zheng and Jin had cooperated to return Wangzi Ding, helping explain why 楚国 would later pressure Zheng.
