The European Union's 'never again' rhetoric, rooted in historical memory, has entered a crisis with the war in Ukraine; the EU's vision of unity based on its values and shared historical narrative has been shattered. The research question of this article is how far-right political actors in Europe have responded to the EU's official memory and security narrative towards Russia and how they have shaped their alternative historical narratives about Russia. This article aims to reveal the current effects of memory-based security concerns in European politics. In this context, Alternative for Germany (AfD), Rassemblement National (RN), and the Hungarian Civic Alliance (Fidesz) were selected for analysis. Data was collected from the parties' official websites, parliamentary transcripts, the official social media accounts of political parties and party leaders, the official YouTube channels of party leaders, and published interviews and media statements. The article employs the concept of mnemonic security to analyze how political actors link their historical narratives to the construction of identity and security. Finally, the study's findings are discussed in relation to the future political implications of memory security.
