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.”

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 societies 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.
