Legitimacy of rule refers to the accepted right of a ruler or government to exercise power and authority over its subjects, often derived from cultural, legal, or moral grounds. This concept plays a crucial role in establishing stability and order within a society, as rulers seek to justify their governance through traditions, ideologies, or divine sanction. In particular, the legitimacy of rule is essential in understanding the Zhou Dynasty's adoption of the Mandate of Heaven, which provided a framework for justifying political power based on the rulerโs ability to maintain harmony and prosperity.
