Women's Sunday was a suffragette march and rally held in London on 21 June 1908. Organised by Emmeline Pankhurst's Women's Social and Political Union (WSPU) to persuade the Liberal government to support votes for women, it is thought to have been the largest demonstration to be held until then in the country. Up to 500,000 women and men from all over the country attended the event, and 30,000 women marched to Hyde Park in seven processions and carried 700 banners, including one that read, "Not chivalry but justice".
