Now in that video on the Shang Dynasty, we talk about how it eventually falls in 1046 BCE, and it falls to the Zhou Dynasty. And the Zhou Dynasty, they defeat the last Shang Emperor, Di Xin, at the Battle of Muyi in 1046. And based on their view of things or current historical accounts, Di Xin became a corrupt ruler, he was under the influence of his consort, and the Zhous say, hey, the reason why we were able to defeat them and overthrow them and establish a new dynasty is because of the mandate of heaven. 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.
