The seminar focuses on an intensive examination of the construction of identity and alterity in the context of war and forced migration. The first part of the seminar is dedicated to sociological and social psychological theories and perspectives on identity, collective identity, and ethnicity. The second part will (theoretically) deal with the specifics of (collective) identity construction in the context of (forced) migration and discuss the analytical potential of the concept of ‘diaspora’ to examine these processes. These theoretical considerations will be complemented by a discussion of empirical studies in this field of research, their key findings and central challenges for future research.
