The significant voice for equality that highlighted gender disparities within the civil rights movement was Betty Friedan. In her seminal work, The Feminine Mystique, published in 1963, Friedan articulated the frustrations of women who felt confined by traditional roles. Her advocacy emphasized the need for women's rights and equality, encouraging activists to address issues like workplace discrimination, reproductive rights, and access to education. Friedan's contributions helped ignite the second-wave feminism movement, which intersected with civil rights issues and sought to challenge systemic gender inequalities in American society, ultimately broadening the scope of the civil rights agenda.
