The Women's Peace Crusade was a grass-roots socialist movement that spread across Great Britain between 1916 and 1918. Its central aim was to spread a 'people's peace', which was defined as a negotiated end to the First World War without any annexations or indemnities. The movement was first established in Glasgow in July 1916, and officially launched on 10 June 1917. It later spread across Great Britain, with demonstrations taking place in Leeds, Bradford, Leicester, Birmingham and Lancashire. Although it gathered a substantial following, the Women's Peace Crusade faced opposition from both the government and police, with members being arrested and reportedly threatened.
