War Resisters' International (WRI) is an international anti-war organization with members and affiliates in over thirty countries. Its headquarters are in London, UK.
War Resisters' International was founded in Bilthoven, Netherlands in 1921 under the name "Paco", which means "peace" in Esperanto. WRI adopted a founding declaration that has remained unchanged:
It adopted the broken rifle as its symbol in 1931.
Many of its founders had been involved in the resistance to the First World War: its first Secretary, Herbert Runham Brown, had spent two and a half years in a British prison as a conscientious objector. Two years later, in 1923, Tracy Dickinson Mygatt, Frances M. Witherspoon, Jessie Wallace Hughan, and John Haynes Holmes founded the War Resisters League in the United States.
Notable members include Dutch anarchist Bart de Ligt, Quaker Richard Gregg and Tolstoyan Valentin Bulgakov. The group had a close working relationships with sections of the Gandhian movement. In January 1948, Mohandas Karamchand Gandhi attended a preparatory meeting for the World Pacifist Meeting he called, at the behest of WRI, and which eventually took place in December 1949. It took the form of 50 international pacifists meeting with 25 of Gandhi's close associates in an "unhurried conference" in Santiniketan, West Bengal.
