In the last decade, Europe has been affected by several crises, which had and still have detrimental consequences for the life of many people, suffering from unemployment, poverty and social exclusion. The special issue seeks to explore how these crises have challenged and promoted solidarities within and between European countries. In the introductory paper, first a typology of different types of solidaritysocial, political and welfareis developed to account for the varied meanings and uses of the term. Second, the origins and scopes of the different types of solidarity and their link to crises are discussed. After introducing the special issue papers, five contributions to the understanding of crises and solidarities are highlighted, namely: the meanings of solidarity are varied and discursively contested; different types of solidarity merge and interact; crises are a necessary, but not sufficient condition for solidarity to emerge; crises alter the scope of solidarity; economic shocks can have long-term effects on solidarity. Thus, crises have led to a reconfiguration of solidarities in Europe.
