Despite the burgeoning literature on coalition work, very little is known about the cooperative potential within social movements. Drawing on archival, interview, and secondary data, we examine cooperation and conflict in the US conservative Christian political movement from 1970 to 1994. We highlight how framing, political elites and intramovement dynamics within the conservative Christian political movement altered the cooperative potential over time. Specifically, we find that the conservative Christian political movement initially had a strong coordinative potential and even engaged in organization building as a way to formalize cross-denominational cooperation. However, as the evangelical wing of the movement sought to build and consolidate its political power, it began to frame issues in ways that reflected a particularized world view regarding the role of the state in fostering a moral society. Other conservative Christian organizations responded by couching their understanding of political issues in their own faith traditions, creating divisions within the movement and ultimately making cooperation impossible. Conceptually, this research broadens how we think about cooperation and points to the importance of specialization and political elites to cooperation within movements.
