The Fridays for Future movement with thousands of young climate strikers counters these statements. The aim of this thesis is to investigate the facilitating role of social media on youth political participation. This thesis analyses how social media contributes to the formation of a collective group identity of social movements, which in turn could lead to collective political action. To answer this question, content analysis of comments on three Instagram posts by Fridays for Madrid have been used, looking at the four foundations of collective group identity: solidarity, emotional attachment, group cohesion and activist-based identification. The results demonstrate the facilitating function of social media in the formation of collective group identity, by enabling more easily and frequently interaction between participants and the social movement compared to offline social movement activities.Show less
