Spring-Autumn to Warring States Political Violence / 春秋战国政治暴力转型

Spring-Autumn to Warring States political violence / 春秋战国政治暴力转型 is the episode’s frame for a change in elite conflict. In 《资治通鉴·周纪》07丨两起刺杀（1）, the host contrasts older aristocratic politics, where defeated heirs might be exiled or allowed descendants, with a harsher Warring States mode where factions kill rulers, ministers, and rival lineages to seize power.

The main source case is 郑国: the ruler kills 子阳, Ziyang’s faction later kills the ruler, and 郑康公 is installed. The concept extends Spring-Autumn Warfare Ritual from interstate combat norms into court politics: rules and status codes still exist, but they are losing force.

《资治通鉴·周纪》07丨两起刺杀（2） makes the sequence concrete by naming 郑繻公 as the killed ruler and by placing this internal violence beside 聂政’s private-revenge assassination and 负黍’s city-control churn.

Key Claims

• The breakdown of ritual constraint changes internal politics as much as interstate war.
• Exile, lineage preservation, and negotiated displacement become less reliable once factions learn that total elimination can work.
• Assassination can operate as state-capture technique, not only as revenge or moral protest.
• The concept is historical-institutional; it complements but is distinct from Political Assassination Ethics / 政治刺杀伦理, which asks when political killing can seem morally intelligible.
