This article examines the question of solidarity in light of recent refugees’ and forced migrants’ arrivals on Greek island shores as the first point of entry to the European Union. It focuses on various community solidarity initiatives emerging in 2015 and how they unfolded over time, until replaced by hostility and indifference following the EU–Turkey deal in March 2016. To account for this transformation, the study, carried out between 2016 and 2018, involved ethnographic work, interviews with local populations, activists, teachers and community leaders, and participant observations primarily in Lesbos, as well as Chios, Leros, and Samos. This article also sheds light on how Greece’s severe economic crisis has compounded anti-migration politics and securitization in recent migratory movements. Drawing on Judith Butler’s ideas of embodied vulnerability and intersubjective relationality, the article theorizes how solidarity evolves when border struggles intersect with deservingness, belonging, and refugees’ and forced migrants’ precarity. It concludes by proposing a psychosocial embodied notion of solidarity as a political strategy to counteract the neoliberal predicament that threatens all life with extinction.
