The Case of Queen Dowager of Qi Installing Prince Jian according to Law

Upon the death of King Xiang of Qi (circa 265 BC), a succession crisis arose. The queen, later honored as Queen Dowager Junwang, insisted that her son Tian Jian, the designated crown prince born of the principal wife, must inherit the throne in strict accordance with the Zhou dynasty’s patriarchal succession law. Several court officials proposed installing the late king’s brother or a different prince, arguing on grounds of capability or seniority. The queen firmly invoked the established legal maxim “sons inherit by status, not merely by age,” maintaining that deviation would breed chaos. She leveraged legal tradition and rallied key ministers to her cause. After intense deliberation, her interpretation prevailed. Prince Jian was formally enthroned as King Jian of Qi, becoming the state’s last monarch. The case was thus resolved through adherence to codified inheritance rules.

Prince Tian Jian was installed as King Jian of Qi, validating the primogeniture rule.

Whether royal succession must strictly follow the primogeniture principle, favoring the son of the principal wife, or could be altered based on the abilities of alternative candidates or the judgment of the court.

The case reinforced the legal sanctity of primogeniture in ancient China, deterred irregular succession attempts, and served as a precedent for imperial succession laws in later dynasties, contributing to dynastic stability.
