Currently one perceives the state as being a rather "fixed" part of many societies. Of course its characteristics and "ideologies" vary, but for example the existence of state is I think more often justified, rather than the anarchist belief of no state.
However, since having the state has certainly started from having no state, then how has the state developed (I understand this is a broad question) and particularly how could the developers of the state legitimize their actions? Particularly, because the state would have to have been developed by some individuals, but how did these individuals claim power over others in order to have the right to decide for others? Or perhaps the development process of the state is so long, starting from some tribal councils, that it has just evolved gradually over a long time.
