Zhou dynasty
The Zhou dynasty replaced the Shang dynasty in 1046 BCE. The kings of this dynasty made the empire a lot bigger. For the first time in the history of China, many people began moving to far away places inside the empire. The Zhou rulers moved the capital from Henan to a place near present-day Xi'an, near the Yellow River. The Zhou Dynasty also brought the theory of the Mandate of Heaven. This theory said that the fact that rulers were in charge proved that the gods wanted them to be in charge. Almost all dynasties of Chinese rulers after the Zhou continued to believe this theory.
