jawDynastic+Cycle

=Dynastic Cycle= The dynastic cycle refers to the process of a dynasty weakening, and another noble family taking over and emerging as a new dynasty. This is how the Zhou came into power. In 1027 B.C., the Zhou people overthrew the Shang to establish their own dynasty. To justify this rebellion, the Zhou leaders claimed that because the Shang king was being foolish and ruling poorly, the gods had taken away his rule and gave it to them. The approval of a king by the gods is called the Mandate of Heaven.
