Women's suffrage in the United Kingdom became a national movement in the nineteenth century. Women were not explicitly banned from voting in Great Britain until the 1832 Reform Act and the 1835 Municipal Corporations Act. Both before and after 1832, establishing women's suffrage on some level was a political topic, although it would not be until 1872 that it would become a national movement with the formation of the National Society for Women's Suffrage and later the more influential National Union of Women's Suffrage Societies (NUWSS). The movement shifted sentiments in favour of woman suffrage by 1906. It was at this point that the militant campaign began with the formation of the Women's Social and Political Union (WSPU). Some have argued the militant suffragettes turned to violence and discredited and postponed votes for women.
