Abstract The Women's Social and Political Union (WSPU), founded in 1903 in Manchester, England, by Emmeline Pankhurst and her eldest daughter, Christabel, has attracted the attention of many scholars. This article explores a neglected theme in that history, namely the daily lives of WSPU militant suffragettes, both outside and inside prison. When discussing this theme, some contrasts and comparisons are also made with that vast number of WSPU members who were non-militant. Despite such differentiation among WSPU members, however, what was reiterated time and time again was their feeling of sisterhood. The bonds between all women, irrespective of any social and political differences, was pervasive in WSPU rhetoric and helped forged a sense of collectivity among WSPU members. Such a message has a relevance for all feminists today.
