The thesis examines the experiences of undocumented people in Athens, analysing the social and institutional configuration of “illegality” and the practices of resistance of these people. It refers to the hierarchical social position that characterizes the lives of these individuals, as well as the forms of victimization they experience from institutions and society. Making use of ethnographic methodology and theoretical tools from Critical Studies of Citizenship and Immigration Autonomy, the research reveals how these individuals challenge the traditional boundaries of citizenship and social inclusion. Avoiding focusing only on their vulnerability and presenting them as a threat or a burden, this research seeks new tools for viewing the refugee phenomenon as a crucial factor in shaping and broadening the debate on human rights and the concept of citizenship through the experiences of these individuals. Furthermore, it documents protests that challenge traditional notions of citizenship and visibility and reconstructs the notion of resistance through everyday practices. The findings of the research underline the importance of the participation of undocumented people in the social fabric and political life, refuting stereotypical notions of passivity. Finally, the thesis employs comics as a reflective narrative tool to delve into the dynamics of the researcher- participant relationship.
