Harvey had long campaigned in political activities for Black advancement through organizations such as the National Association for the Advancement of Colored People before she became involved in Women Strike for Peace. Her involvement in WSP, however, grew from her founding of the Mississippi-based women’s group Womanpower Unlimited, set up as a Citizens’ Committee to aid the Freedom Riders in the spring of 1961.
Clarie Collins Harvey deftly understood that women’s empowerment and racial equality entailed a broader campaign that encompassed peace and disarmament. This awareness led her to collaborate with WSP in the early 1960s. Womanpower Unlimited came, for some in WSP at least, to awaken them to the plight of civil rights activists. Although WSP generally distanced itself from the civil rights movement in the early 1960s, Harvey’s involvement with the group’s activities aided the gradual turn to a more comprehensive and radical critique of US politics and society.
WSP sent Harvey as one of four delegates of its to the World Without the Bomb Conference held in Accra, Ghana, between June 21 – 28, 1962. She attended along with Frances Herring, Selma Sparks, and Nancy Mamis.
