Peace camps are a form of physical protest camp that is focused on anti-war activity. They are set up outside military bases by members of the peace movement who oppose either the existence of the military bases themselves, the armaments held there, or the politics of those who control the bases. They began in the 1920s and then became world famous in 1982 due to the tremendous worldwide publicity generated by the Greenham Common Women's Peace Camp. They were particularly a phenomenon of the United Kingdom in the 1980s where they were associated with sentiment against American imperialism but Peace Camps have existed at other times and places since the 1920s.
In the United Kingdom, people came to live outside military bases at protest camps in order to witness their opposition to and nonviolently protest against the presence of nuclear weapons in Europe that were directed against the then Soviet Union by the United States, calling for nuclear disarmament. The women at Greenham Common Women's Peace Camp were particularly against the placing of US cruise missiles there, something they claimed made the area a direct target of Soviet Union aggression. During the 1980s the United States Air Force had land-based cruise missiles at several of the above locations, not only Greenham Common; they have since been moved back to the United States, though there remains a US military presence in the UK, and the UK continues to possess and develop nuclear weapons itself. Due to these factors the concept of the peace camp remains alive today; and because of the presence of Faslane Peace camp there has continuously been at least one peace camp outside a military base in the UK since 1982.
