The recent rise of the far-right ‘Alternative für Deutschland’ (AfD) in Germany has puzzled researchers. How did demands around cultural homogeneity and the need to be protected from ‘dangerous’ immigrants become acceptable in the mainstream when previously they were not? Crucially, understanding political change is paramount for discourse theorist Ernesto Laclau, who considers ‘demands’ as pivotal for the construction of political identities. Yet, the notion is underdeveloped in his writings. I discuss the aporias in Laclau’s understanding of demands and probe (...) how far we can take Laclau in theoretically accounting for the emergence of demands. The concepts of horizon and dislocation are most helpful in this regard. I then utilise those concepts to analyse demand emergence in the ‘Leitkultur’ (leading culture) debate. I show how the horizon on which these demands are inscripted changed over the years, with a culturalistic discourse becoming dominant. There, following a dislocatory public debate of a non-fiction bestseller by career bureaucrat Thilo Sarrazin, integration was increasingly framed as problematic and foreigners needing to shed unintegratable parts of their own culture to assimilate to a German Leitkultur. I argue that acts of mainstreaming like these allowed the AfD to make their formerly radical demands seem credible. (shrink)
