The Campaign for Nuclear Disarmament (CND) is an organization that advocates unilateral nuclear disarmament by Britain. It also campaigns for international nuclear disarmament and tighter international arms regulation through agreements such as the Nuclear Non-Proliferation Treaty. It opposes military action that may result in the use of nuclear, chemical or biological weapons and the building of nuclear power stations in the UK.
CND was formed in 1957 and has periodically been at the forefront of the peace movement in the United Kingdom over half a century. It claims to be Europe's largest single-issue peace campaign. Since 1958, it has organised the Aldermaston March, which is held over the Easter weekend from Trafalgar Square, London, to the Atomic Weapons Establishment near Aldermaston.
