War Resisters' International was founded in 1921 under the name "Paco". It was and is based on the WRI declaration:
War is a crime against humanity. I am therefore determined not to support any kind of war, and to strive for the removal of all causes of war
War Resisters' International exists to promote nonviolent action against the causes of war, and to support and connect people around the world who refuse to take part in war or the preparation of war. On this basis, WRI works for a world without war.
