The Case of Duke Li of Jin Executing the Three Xi

In the Spring and Autumn period, Duke Li of Jin, alarmed by the overwhelming power of the Xi clan—three brothers (Xi Qi, Xi Chou, Xi Zhi) who monopolized court and military affairs—plotted their elimination. Goaded by his favorites Xu Tong, Yi Yangwu, and Chang Yujiao, who bore personal grudges, the duke accused the Xi of sedition. In the winter of 574 BC, during a court session in the capital Jiang, armed men seized the three ministers and summarily executed them in the hall, later massacring their families. The duke intended to also kill two other powerful nobles, Luan Shu and Zhonghang Yan, but hesitated. Within months, Luan and Zhonghang Yan retaliated by capturing and assassinating Duke Li in 573 BC. The episode was not a judicial proceeding but a bloody factional purge that vividly exposed the breakdown of ducal authority and the ferocious rivalry among Jin's noble houses.

No formal trial occurred. Duke Li ordered the summary killing of Xi Qi, Xi Chou, and Xi Zhi, along with the extermination of their clans. Shortly afterward, the surviving nobles Luan Shu and Zhonghang Yan mounted a counter-coup, imprisoned Duke Li, and had him assassinated, ending his reign.

Whether the Three Xi truly posed a mortal threat to the state or were victims of slander and the duke's paranoia; whether Duke Li's extrajudicial slaughter was a legitimate defense of the throne or an act of tyrannical violence; and the moral and legal validity of executing high nobles without trial within the Zhou feudal framework.

The purge shattered the fragile balance between the Jin ducal house and the ministerial families, accelerating the decline of central authority. It demonstrated the fatal consequences of arbitrary rule and intensified the power consolidation by noble clans, eventually leading to the partition of Jin among the Han, Zhao, and Wei houses. The event became a lasting cautionary example in Chinese political thought on the dangers of unchecked executive violence and the erosion of feudal hierarchy.
