This thesis investigates the use of enemy images by using a case study of Czech far-right politician Tomio Okamura. In order to achieve its purpose, it makes use of a theoretical framework, based on the five speech legitimization strategies created by Antonio Reyes, as well as a mixed methods single case study, undertaking both a qualitative and a quantitative analysis to showcase how he uses enemy images and which groups he uses as his enemies. This is accomplished by looking at the 49 Facebook posts made by Okamura in the week leading up to the Czech 2021 parliamentary election. The study finds that Okamura mainly utilizes four distinct enemy images, often in connection with each other, with the EU and ‘the West’ being the most frequent one, and that he furthermore, in a majority of his posts, uses rhetoric and strategies closely resembling Reyes’ theories to successfully employ them.
