This thesis presents an ethnographic and practice-based investigation on Infrastructures of Caring Citizenship (ICCs). The term is coined in this same research work and elaborated through a situated study of four specific instances located in Athens, Greece, during the austerity regime imposed in the country (2010-2018) in the wake of the international banking crash of 2008. Broadly, it refers to self-organised initiatives of provision of welfare and social protection, as well as of deliberative struggle against processes of dispossession of the means of subsistence and of rights in urban contexts in crisis. Crisis in this thesis defines the context but also constitutes a conceptual site for interrogation in itself. For this endeavour, four dimensions are distinguished, namely the imaginary, the empirical-experiential, the subjective and the critical-insurgent. The concepts of care, citizenship and infrastructure, which I interrelate, are used as a particular lens to look at contemporary crises, as well for the examination of the four ICCs that comprise the field of this thesis. This two-level theoretical framework articulates my construction – and de-construction – of “Athens-in-crisis”, which is treated as a backdrop as much as a medium of many of the transformations that take place in the city during this period, including the emergence of the ICCs.
