The Mandate of Heaven.

Explanation:

The Mandate of Heaven was the concept that rulers were bestowed a right to rule by Heaven, and that this mandate granted legitimacy to a dynasty. For one to maintain the Mandate of Heaven, they were to govern by moral societal norms. Those who governed immorally would be considered to have forfeited their mandate; ultimately leading to political upheaval and a new dynasty claiming the mandate.

A famous example of the Mandate of Heaven being used to overthrow a dynasty is the case of 1046 BCE, in which the Zhou people overthrew the wildly immoral Shang dynasty, in turn claiming the mandate and birthing the Zhou dynasty.
