天命
Intrinsic to the concept of the Mandate of Heaven was the right of rebellion against an unjust ruler. The Mandate of Heaven was often invoked by philosophers and scholars in China as a way to curtail the abuse of power by the ruler, in a system that had few other checks. Chinese historians interpreted a successful revolt as evidence that Heaven had withdrawn its mandate from the ruler. Throughout Chinese history, times of poverty and natural disasters were often taken as signs that heaven considered the incumbent ruler unjust and thus in need of replacement.
