Non-violent Revolution and Collective Action

People generally preassume revolution with violence and anarchy.But,in the history of civilization many revolutions and movements have been successfully accomplished through non-violence.
Our approach to nonviolence and nonviolent opposition reflects an alternative understanding of power in the modern world.Social scientists commonly follow Weber in assuming that power derives from the legitimacy to use violence and coercion possessed by those controlling the state,who can "realise their own will in a communal action even against the resistance of others"(Weber 1946:180).
At the same time culture of non-violent opposition transforms human relationship defined by love,dialouge and cooperation.The purpose of non-violent opposition is not merely to take over the control of states-and replace one tyranny with another-but to expand the power to promote social justice within states, between states and societies,within societies and between societies.
