Frames of Protest brings together important empirical research and theoretical essays by leading sociologists, political scientists, and media specialists that focus on social movement frames and framing practices. Frames are new ways of understanding political and social relations that emphasize injustice and the need for change. As such, they are crucial for the development of social movements and protest. Frames of Protest is the only book to focus exclusively on this major research perspective in social movement and protest studies. Thirteen chapters encompass the major themes in the framing perspective to offer a state-of-the-art review. Three chapters present evidence for the determining influence of framing in social movement mobilization. Next, framing activities by the state and the mass media are analyzed. Then, two research reports examine the effect of political opportunities on framing-in Poland under the Communists and in New York City’s ethnic politics. Several chapters by leading theorists present a lively debate about the relationship of ideologies to collective action frames. The book closes with a hands-on discussion about analyzing textual materials and interview transcripts to do frame analysis that lends itself to longitudinal and cross-case comparisons.
