But first, let's see an example of the Mandate of Heaven in action. So the Qin dynasty only lasted 38 years, but it's one of the most important dynasties in Chinese history, so important, in fact, that it gave the place its name, Qin. Uh. Can I just tell you guys that we literally just spent 20 minutes on that shot? We shot it like 40 times. Stan, you are in love with puns. The accomplishment of the Qin was to reunify China under a single emperor for the first time in 500 years, ending the Warring States period.
