First-wave feminism was a period of feminist activity and thought that occurred during the 19th and early 20th century throughout the Western world. It focused on legal issues, primarily on securing women's right to vote. The term is often used synonymously with the kind of feminism espoused by the liberal women's rights movement with roots in the first wave, with organizations such as the International Alliance of Women and its affiliates. This feminist movement still focuses on equality from a mainly legal perspective.

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.
