The Cross-National Diffusion of Movement Ideas

Current theory and research on social movements continue to treat these movements as discrete entities, rather than to focus on the ways in which activists in one struggle borrow elements from other similar groups. With its emphasis on the spread of information or other cultural elements, the diffusion literature represents a potentially fruitful starting point for theorizing about the transfer of ideas or tactics from one movement to another. Drawing on this literature, the authors sketch a model of the cross-national diffusion of movement ideas that emphasizes (1) the role of direct relational ties in encouraging an initial identification of activist-adopters in one country with activist-transmitters in another and (2) the role of nonrelational channels as the principal means of information transmission once this initial identification is established. The authors then use the case of the American and German New Left to illustrate the utility of the approach for the study of cross-national diffusion.
