The mandate of heaven is this idea that will be incorporated by the Zhou Dynasty and then becomes part of Chinese culture and tradition for thousands of years after that. Heaven in this sense is not a place in the clouds that some might imagine in a Western tradition. It's really, you could view it as a guiding force of the universe. And it's this idea that if leaders become incapable, they become correct, that this guiding force of the universe will throw them out and put more capable leaders in power. And so King Wu of Zhou, who defeats Di Xin at the Battle of Muyi, he invokes this mandate of heaven and will continue to be invoked throughout the Zhou Dynasty. Now, the Zhou Dynasty is going to be a very long-lasting dynasty, but it is not centralized. It can be described as kind of a feudal system.
