Since the Schengen Convention and the gradual abolition of checks at common borders, a discussion on solidarity within the European asylum policy has been raised. The purpose of this diploma thesis is to investigate the significance of solidarity in European law from a legal perspective. Does solidarity constitute a legal obligation or is it simply a political demand within the European asylum policy? Furthermore, this thesis provides expertise on the legal integration of solidarity and demonstrates its specific relevance in various areas. There is a particular focus upon the Common European Asylum System with regard to the idea of solidarity. Additionally, this thesis illustrates that there are political demands for more solidarity, as well as the stances taken by European institutions and the Member States regarding solidarity in the asylum policy. The final section provides a concluding evaluation of whether solidarity should be classified as a legal obligation.
