To what extent was the success of the Civil Rights movement due to Non-violent action

There are a number of conflicting arguments regarding the use of 'non-violent' action in the 1960s Civil Rights movement. These arguments fall under a number of different categories. An important argument is the validity of the phrase 'non-violent' action, as Martin-Luther King was accused of deliberately provoking violent reactions multiple times. In addition, the difference between 'non-violent action' and resistance to violence against black protestors. Finally, the relevance of legislative movements such as the NAACP must be considered as having an influence over the ultimate success of the Civil rights movement in the 1960s.One example of the success of the Non violent movement was the Birmingham march in May 1963
