I believe that some of the actions that were taken by civil rights leaders was in general a non-violent approach however some started taking a militant approach because the demonstrations had not really helped them get their voice out to the public. Some did peaceful demonstrations such as sit ins. Where they would go into restaurants and sit quietly while dressed professionally. There was a lot of violence during the 1960s. Hopefully this helps.
In the mid-1960s, civil rights leaders shifted towards a more confrontational approach, influenced by figures like Malcolm X and the emergence of the Black Power movement. This period marked a call for immediate action and self-determination, diverging from earlier nonviolent strategies. The assassination of key leaders and the cultural influence of Black Power further fueled this change in tactics and ideology.
