The concept of the common, found in Hardt and Negri, provides the possibility of theorising struggle that avoids the critiques that suggest Empire remains intangible, ethereal and postmodern. The concept, however, remains fragmentarily developed by the authors themselves, and is rarely the subject of sustained analysis in the secondary literature. Therefore, in order to substantiate the concept, I consider the common through three distinct moments which I identify as the urban, digital and political moments. This task is achieved through theoretical interlocutions and reflections on the 2011 Occupy movement. Throughout this thesis, and through each moment of the common, I argue that the concept must be understood as distinctly physical. Firstly, struggles over the urban common revolve around the physical (re)production of ideas, knowledge, culture and relationships in urban environments. Whilst the digital common often implies a lack of physicality, I argue that the common offers a means of thinking social media and perpetual connectivity primarily as a process of transforming the way humans engage with one another and their environments, and the radical possibilities therein. I argue that these moments of the common necessitate the development of an appropriate political moment of the common. Through centring on the physicality of struggle, Hardt and Negria's concept of the common is substantiated whilst contributing to wider debates in the field of radical theory and social movements.

As a result of the #MeToo movement in Sweden, #sistabriefen was created to represent the women, non-binaries and trans-persons working within the communications industry. This study analyzes the dynamics and identities of the #sistabriefen group members on their private social media platform. The analysis incorporates The Logic of Connective Action by Bennett and Segerberg (2012), and two complementary Social Identity Perspectives; Social Identity Theory and Self-Categorization Theory (Hogg & Terry, 2001; Hogg & Reid, 2006). The study consisted of 23 interview participants, and a qualitative content analysis over the course of five months. This research assesses how members are motivated to participate in the #sistabriefen group, how they identify themselves within the group, and how the group features affect members’ involvement. The findings of the research indicated that digital social movements have the potential to effectively mobilize social change.

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.
