Josephine Butler, English feminist and social reformer (died 1906)

Josephine Elizabeth Butler was an English feminist and social reformer in the Victorian era. She campaigned for women's suffrage, the right of women to better education, the end of coverture in British law, the repeal of the Contagious Diseases Acts, the abolition of child prostitution and an end to human trafficking of young women and children into European prostitution.

Feminism is a range of socio-political movements and ideologies that aim to define and establish the political, economic, personal, and social equality of the sexes. Feminism holds the position that modern societies are patriarchal—they prioritize the male point of view—and that women are treated unjustly in these societies. Efforts to change this include fighting against gender stereotypes and improving educational, professional, and interpersonal opportunities and outcomes for women.

Reformism is a type of social movement that aims to bring a social or also a political system closer to the community's ideal. A reform movement is distinguished from more radical social movements such as revolutionary movements which reject those old ideals, in that the ideas are often grounded in liberalism, although they may be rooted in socialist or religious concepts. Some rely on personal transformation; others rely on small collectives, such as Mahatma Gandhi's spinning wheel and the self-sustaining village economy, as a mode of social change. Reactionary movements, which can arise against any of these, attempt to put things back the way they were before any successes the new reform movement(s) enjoyed, or to prevent any such successes.
