The Peace Pledge Union is the oldest secular pacifist organisation in Britain.
Since 1934 it has been campaigning for a warless world. From anti-bombing campaigns during WW2 to protest at the remote controlled military drone assassinations of today. From the militarisation of Armistice Day in the 30s to the militarisation of society today.

It has links to resources on teaching and learning materials on subjects including Conscientious Objection, Pacifism, Genocide, Non-violence in WW2, Poetry and war and Remembrance.
However there is no search facility and the resources are not classified by age group. Most of them seem to be more appropriate for secondary education.
