How is solidarity understood by the people who practice it actively and daily? What is the role of solidarity in reconciling the relationship of individuals with the collective demands of communities that fight for the rights of others? Based on a variety of anthropological, sociological, and philosophical writings as well as ethnographic research, Maria Giannoula takes an elaborated look at the emotional and spiritual aspects of political participation within an activist group in Greece in the 2010s. This study is a valuable resource for those researching social movements and alternative communities, focusing on the ways in which individuals organise their own forms of activism.
