This article researches the extent to which far-right movement parties have influenced foreign policy in a Western democracy (Greece). Our study looks at the far-right movement party Golden Dawn on the long-lasting dispute over the naming of Northern Macedonia. Other than expected, we observe that extremist far-right movement parties in parliament possess a higher capacity to influence the discourse of centre-right parties regarding foreign policy issues than populist far-right parties. We attribute this pattern of nativist frames’ contagion to the dynamic component of movement parties that can make them more virulent in their discourse and more inventive in their protest actions than other parties. Our research shows how far-right movement parties discursively contribute to the production of state power in territorial forms. It contributes to the study of social movements, of the far right and of critical geopolitics, opening up future research avenues for the study of the contagion effects of far-right movement parties.
