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 19th century, 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.
