How did the rulers of native American European and African empires and kingdoms secure and sustain their power

There are various ways on how the rulers of native American, European, and African empires and kingdoms secure their power. Native American’s chief or local leaders usually kept their powers through their people’s respect or through violence. European’s follow the nobility rule where mostly peasant families are hardly benefited, and African builds empires, kingdoms, mini-states that people often suffered because of the bad decisions.
