Nostalgia can be triggered not only by personal recollections but also by exposure to narratives or images evoking desirable pasts, more or less fictional, and inducing feelings of longing for them. We analyze the institutional and semiotic machinery involved in the cultural construction of nostalgia in Poland and its role in generating sentiments that predispose people to support populist—particularly right-wing populist—ideology. While various political options use semiotic vehicles of nostalgia designed to engender nostalgic sentiments, we argue that there are systematic differences of content and form between politically useful invocations of nostalgia, related to the ideology of their proponents. We further posit that right-wing populist nostalgia invokes not only national greatness but also national innocence. We also identify specific features of such nostalgic discourses. The empirical material for our four cases ranges from textual and film narratives, through images and performances, to large-scale exhibitions and museal projects. To analyze their content and determine the form of politicization we build upon the conceptual apparatus developed by Svetlana Boym (reflective versus restorative nostalgia), Jan Assmann (communicative versus cultural memory), and Northrop Frye (low mimetic versus high mimetic narrative forms). The analysis relies on Geertzian “thick description” and the extended case study method
