Dynastic Legitimacy Backfire / 王朝合法性回旋镖

Dynastic legitimacy backfire / 王朝合法性回旋镖 is the central mechanism in 126.王莽之死：神圣帝国的回旋镖，和回旋镖的回旋镖. The episode argues that Western Han rulers strengthened their authority through Mandate of Heaven Legitimacy / 天命合法性, but by doing so also made it thinkable that Heaven could abandon the Liu family and validate 王莽.

The backfire is not only conceptual. Once succession trouble, disasters, court anxiety, and 祥瑞 accumulated, sacred legitimacy became a weapon that could be turned against the dynasty that had depended on it.
