Radical Sisters offers a fresh exploration of the ways that 1960s political movements shaped local, grassroots feminism in Washington, D.C. Rejecting notions of a universal sisterhood, Anne M. Valk argues that activists periodically worked to bridge differences for the sake of alleviating women's plight, even while maintaining distinct political bases. While most historiography on the subject tends to portray the feminist movement as deeply divided over issues of race, Valk presents a more nuanced account, showing feminists of various backgrounds both coming together to promote a notion of "sisterhood" and being deeply divided along the lines of class, race, and sexuality.
