This article untangles competing conceptualisations of nostal- gia and identifies a specific form of collective-restorative nostalgia as politically significant. We argue that the link between resentment and this type of nostalgia emerges from their joint critique of the socio-political realities of the present. Nostalgia provides spatial and temporal orienta- tions for a group's experiences of resentment through highly selective recollections of the heartland and an idealised golden age. We hypothesize that nostalgia leverages the heartland and the golden age to formulate claims for recog- nition and restored status on behalf of those who feel left behind by late modernity. Next, the article uses structural equation modelling and the 2019 Belgian National Election Study to reveal how resentment (consisting of ontological insecurity, group relative deprivation, and powerlessness) mediates between structural characteristics and nostalgia. Our findings suggest that each component of resentment individually contributes to explaining the nostalgia of less educated and economically deprived individuals. ; SCOPUS: ar.j ; info:eu-repo/semantics/published
