Peace movements' newness is exaggerated; religious pacifists predate modern wars. [contrarian]
Labour and free speech/democratic movements are “old”: that is, they were well-established in certain forms prior to the current century. The other types of social movements are newer, in the sense that they have come to increasing prominence in relatively recent years. Their newness, however, can be exaggerated. Peace movements have as their site of struggle the arena of control of the means of violence, including both military and police power. “Peace” here has to be seen, like “democracy,” as a contested concept central to the dialogues which such movements enter into in the fields of action they share with organisations such as the military or the state. Pacifist movements of some kinds, normally influenced by religious values, date back to the early origins of industrialised war. If they have assumed a particular significance today, this is undoubtedly in large part an outcome of the growth in high-consequence risks associated with the outbreak of war, with nuclear weaponry forming the core component in contemporary times.
