The purpose of this research is to get a better understanding of the impact of the Stockholm Fire Festival on the cultural integration of immigrant communities, and particularly its impact on the sociocultural integration of individual participants into Swedish society. The methodological approach is mixed-methods, consisting of participant observation, and a selected part of the data from 280 completed surveys based on answers to open-ended and closed-ended questions. The results indicate that participation in the festival and its celebration have a positive impact at the macro and ethnic community levels in terms of recognition of the festival by the host society, and thereby cultural integration, identity and inclusion of the ethnic community in the entire society. However, the results do not support the idea that participation in this festival has a positive impact on the sociocultural integration of the individual participants into society. Sociocultural integration presupposes intercultural encounters between immigrant individuals, between them and other ethnic groups (including the natives). It is evident that this festival cannot create such a platform for individual participants. This research contributes to the existing body of research on immigrant-oriented festivals in Western societies and strengthens the debates on migration, inclusion, integration, multiculturalism and interculturalism.
