After her husband died in 1898, Pankhurst founded the Women's Social and Political Union (WSPU), an organisation dedicated to "deeds, not words". The group became infamous when its members smashed windows and assaulted police officers. Pankhurst, her daughters, and other WSPU activists were sentenced to repeated prison sentences, where they staged hunger strikes to secure better conditions. As Pankhurst's oldest daughter Christabel took the helm of the WSPU, antagonism between the group and the government grew. Eventually arson became a common tactic among WSPU members, and more moderate organisations spoke out against the Pankhurst family. In 1913 several prominent individuals left the WSPU, among them Pankhurst's daughters Adela and Sylvia. The family rift never healed.
