First to the Party: The Group Origins of the Partisan Transformation on Civil Rights, 1940–1960

One of the most momentous shifts in twentieth-century party politics was the Democratic Party's embrace of civil rights. Recent scholarship finds that this realignment began as early as the 1940s and traces it to pressure groups, especially organized labor. But such scholarship does not explain why labor, which was traditionally hostile to African Americans, began to work with them. Nor does it ascribe agency to the efforts of African American pressure groups. Focusing on the National Association for the Advancement of Colored People (NAACP) and the Congress of Industrial Organizations (CIO), this article attempts to fill these gaps in the literature. It explains why civil rights and labor leaders reassessed their traditional animosities and began to work as allies in the Democratic Party. It further shows how pressure from the new black-blue alliance forced the national Democratic Party to stop straddling civil rights issues and to become instead the vehicle for promoting civil rights. NAACP and CIO leaders consciously sought to remake the Democratic Party by marginalizing conservative Southerners, and eventually succeeded.
