The Zhou Dynasty

Explanation:  Zhou Dynasty overthrew the Shang Dynasty and used the Mandate of Heaven as justification.

The Zhou created the Mandate of Heaven: the idea that there could be only one legitimate ruler of China at a time, and that this ruler had the blessing of the gods. They used this Mandate to justify their defeat of the Shang, and its subsequent rule.
