Weber was one of the first Sociologist to define power.
He said there were 3 types of power; Traditional, Charismatic and coercive.
Traditional – This is the power someone gains because of traditions and customs. For example, a King inherits power purely because he is born into power. Similarly, a teacher naturally has power over a class because he or she is the teacher!
Charismatic – This is when someone gains power because of their personality and charisma. For example many great political leaders are in that position of power because they have a personality which draws obedience from their followers
Coercion – This is the power gained by using fear, abuse and threats. An example of this would be political leaders who imprison or kill any opposition
