Abstract
Social movement organizations (SMOs) engage in the formation of public policy and social beliefs by framing issues and events for the public. These framing activities may offer an alternative source of knowledge and challenge status quo definitions of important social issues. Analyzing the statements and press releases of four peace movement organizations during the seven months of military escalation and war in the Persian Gulf in 1990 and 1991, this article explores the structure and content of social movement framing of a specific event. Findings suggest that the shape and content of the frames used by these SMOs are rooted in a complex amalgamation of each organization's historical and public identity, intended audiences, and contemporary motivations and organizational goals. The collective identity of an organization influences the shape and content of the organization's framing activities. The organizations studied made use of their specific structural and organizational strengths as part of a credentialing process, wherein they shaped their oppositional voices so they could be heard and accepted by specific audiences. This was in turn a matter of the organization's historical practice, the ways it presented that history, and how it constructed its con temporary collective identity (e.g., as Quakers or as Catholic peacemakers). All of this is done with a view toward claiming a voice in the public debate, a voice that may help the SMO create oppositional bases of knowledge, influence public policy, sustain and embolden members, and establish a historical record of opposition.
