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.

Betty Friedan was an American feminist writer and activist. A leading figure in the women's movement in the United States, her 1963 book The Feminine Mystique is often credited with sparking the second wave of American feminism in the 20th century. In 1966, Friedan co-founded and was elected the first president of the National Organization for Women (NOW), which aimed to bring women "into the mainstream of American society now [in] fully equal partnership with men.”
