The event that catalyzed the feminist movement in America during the 1960s was the publication of Betty Friedan's book, "The Feminine Mystique." This influential work critiqued the societal expectations placed on women, particularly the ideal of domesticity, and sparked widespread discussion about gender inequality. Friedan's arguments resonated with many women who felt unfulfilled in traditional roles, leading to the formation of feminist organizations and activism advocating for women's rights. The movement gained momentum, addressing issues such as workplace equality, reproductive rights, and legal reforms.
