This thesis explores the interplay between digital social movements and political parties on social media. The overarching aim of the thesis is to contribute to the understanding of how the digitalization of the electoral arena has transformed social movements, and how this affects the political parties' perceptions of them. The theoretical framework consists of three analytical lenses to conceptualize this interplay, these are George and Leidner’s (2019) categorization and classification of digital activism, Gunnar Sjöblom’s (1968) theory on partystrategies in a multiparty system, and Anne Kaun’s (2017) concept desynchronization. Acombination of methods is used, including network analysis and interviews, to explore this interplay. The results of the study indicate that there is a desynchronization in the practices of digital social movements and Swedish political parties.
