Using a multimodal discursive approach, this study explores how the COVID-19 pandemic is constructed and used in press reportage to mobilize intergroup relations and national identities. We examine how press reporting about the development of COVID-19 in Sweden is cast as a matter of nationalism and national stereotyping in the Finnish press. The data consist of 183 images with accompanying headlines and captions published in two Finnish national newspapers between January 1 and August 31, 2020. We found three multimodal rhetorical strategies of stereotyping: moralizing, demonizing, and nationalizing. These strategies construct discourses of arrogant, immoral, and dangerous Swedes sourcing from national stereotypes. The study contributes to current knowledge about the work on national stereotypes by illustrating how they are used in media discourse to achieve certain rhetorical ends, such as to persuade, mitigate, or justify intergroup relations. Furthermore, the study offers insight into the multimodal constructions and functions of stereotypes.
