This is Tang(One of the tribal leader and the ruler of his tribe) Planned for a long time to overthrown the Xia Dynasty.
The last ruler of Zia Dynasty is Jie, or refer as Jie of Xia. He is an oppressive ruler, people did not rebel because there is a saying that king is forever king, and dynasty forever ruled. But Jie never won the love of people anyway. People thought there were no changing it.
Tang did not believe that, he took out Jie by force. 11 battle that completely destroyed the rotting dynasty. (The people either supported or bystanders because they did not like Jie, after all, it's for one's better life) He(Tang) did not, however, kill Jie. Instead exile and later died of either starvation of disease (more likely starvation, it's said that Jie is stronger than any beast) Jie was on throne for 53 year.There is consequence, Tang's action broke the rule(this Xia Dynasty is the first dynasty but not the first to apply this rule, earlier tribe before also did)Shang, Tang created, is later replace by Zhou because of that, and Zhou taken by Qin state for the same reason.The Mandate of Heaven is good for spreading words about the ruler, but the people who wanted the throne for themselves never cared, so the effect of Mandate of Heaven really depends.
