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.

The feminist movement, also known as the women's movement, refers to a series of social movements and political campaigns for radical and liberal reforms on women's issues created by inequality between men and women. Such issues are women's liberation, reproductive rights, domestic violence, maternity leave, equal pay, women's suffrage, sexual harassment, and sexual violence. The movement's priorities have expanded since its beginning in the 1800s, and vary among nations and communities. Priorities range from opposition to female genital mutilation in one country, to opposition to the glass ceiling in another.
