How did the zhou explain the right to rule?

The Zhou dynasty justified their right to rule through the concept of the "Mandate of Heaven," which posited that heaven granted emperors the right to govern based on their ability to uphold moral integrity and govern justly. If a ruler became corrupt or failed to fulfill their duties, it was believed that they would lose this mandate, justifying rebellion and the rise of a new ruler. This ideology reinforced the legitimacy of the Zhou and provided a moral framework for political authority in ancient China.
