This article explores the strategic (mis)use of historical memory by populist political actors, focusing on George Simion, leader of the Romanian radical-right party Alliance for the Unity of Romanians. Through a detailed case study of the Valea Uzului Cemetery controversy, the research examines how populist movements construct and disseminate exclusionary historical narratives to mobilize affective publics, reinforce nationalistic ideologies, and generate political support. Drawing on qualitative analysis of Facebook comments and posts, the study investigates how memory is weaponized to polarize public opinion and elevate a simplified, antagonistic vision of history. The Valea Uzului case exemplifies how war cemeteries and commemorative practices can be transformed into symbolic battlegrounds for political gain. The digital environment serves as a key vector for radicalization, emotional amplification, and narrative reinforcement. Ultimately, this research highlights the critical role of memory in populist politics and the power of social media in shaping historical perception. It calls for further comparative investigation into how such mnemonic strategies impact democratic processes, interethnic relations, and the broader politics of remembrance in contemporary Europe.
