according to the zhou the shang kings had lost their mandate of heaven because
Mandate of Heaven The prosperous Shang dynasty saw its rule filled with many outstanding accomplishments. Notably, the dynasty lasted for a considerable time during which 31 kings ruled over an extended period of 17 generations. During this period, the dynasty enjoyed a period of peace and tranquility in which citizens could make a good living. The government was originally able to control most of its internal affairs due to the firm support provided by the people. As time went on, however, the rulers' abuse of the other social classes led to social unrest and instability. The corruption in this dynasty created the conditions necessary for a new ruling house to rise â€”the Zhou dynasty. Rebellion against the Shang was led by Zhou Wu. They created the Mandate of Heaven to explain their right to assume rule and presumed that the only way to hold the mandate was to rule well in the eyes of Heaven. They believed that the Shang ruling house had become morally corrupt, and that the Shang leaders' loss of virtue entitled their own house to take over. The overthrow of the Shang Dynasty, they said, was in accordance with the mandate given by Heaven.[4]
