The Mandate of Heaven could have stayed a piece of dynastic propaganda, a story rulers told to explain how they got the throne. It became something sharper once the philosopher Mencius stated its corollary in plain terms: the people matter more than the altars of soil and grain, and the altars matter more than the ruler. Read the other way round, that ranking is a license. If the ruler is the least important of the three, then a ruler who governs so badly that Heaven withdraws the Mandate is no longer a king in anything but name, and removing him is not treason against the state but loyalty to it. Mencius was not describing an abstract possibility. The doctrine gave the Chinese political tradition a built-in theory of legitimate rebellion at a time when most monarchies in the world offered their subjects no comparable argument; a European peasant who rose against a king believed by divine right to rule was defying God's own choice, while a Chinese peasant who rose against a tyrant could claim Heaven had already made the choice for him.
