List of peace activists


This list of peace activists includes people who have proactively advocated diplomatic, philosophical, and non-military resolution of major territorial or ideological disputes through nonviolent means and methods. Peace activists usually work with others in the overall anti-war and peace movements to focus the world's attention on what they perceive to be the irrationality of violent conflicts, decisions, and actions. They thus initiate and facilitate wide public dialogues intended to nonviolently alter long-standing societal agreements directly relating to, and held in place by, the various violent, habitual, and historically fearful thought-processes residing at the core of these conflicts, with the intention of peacefully ending the conflicts themselves.
