Direct Action Committee
The Direct Action Committee Against Nuclear War or the Direct Action Committee (DAC) was a pacifist organisation formed "to assist the conducting of non-violent direct action to obtain the total renunciation of nuclear war and its weapons by Britain and all other countries as a first step in disarmament". It existed from 1957 to 1961, when it was largely subsumed into the Committee of 100, but it was, historian Martin Shaw argues, the original driving force of the mass movement against nuclear weapons in Britain.
