ABSTRACT In times of crisis, interpersonal and group solidarity often emerge as people face critical challenges that threaten their survival. However, it remains unclear whether spontaneous solidarity practices are enough to effectively face such crisis situations. In this paper, we argue that to be fully effective, solidarity must be deployed through all its political tiers, from interpersonal and group relationships to institutional and legal normativity. We contend that solidarity relations can only reach an enduring goal if they solidify into stable (...) principles that can be acknowledged and enacted at the institutional level. Through an examination of recent literature and concrete case studies, the paper investigates the linkages and mutual dependencies between the various levels of solidarity developed throughout the COVID-19 pandemic. This analysis may allow us to answer the question of whether a “Multilevel European Solidarity” is a realistic goal, and what is required to achieve it. (shrink)
