Abstract: This paper examines the adaptation and proliferation of antisemitic narratives on Telegram during the Russian-Ukrainian war, tracing their evolution from historical myths to digital propaganda. Through a qualitative analysis of Telegram channels in Russian and Ukrainian, we explore how classical antisemitic tropes such as conspiracy theories about Jewish global control, Holocaust denial, and accusations of dual loyalty are repurposed to shift blame for the war onto Jews. Our findings reveal a multilayered process of blame-shifting operating across historical, social, national, and global levels, positioning Jews as instigators of conflict to deflect civic and political responsibility from Russians and Ukrainians. We argue that this antisemitic rhetoric serves as a tool of social manipulation and political deflection, embedded in diverse nationalist and conspiratorial digital environments. By embedding these narratives within Telegram’s unregulated and virally oriented ecosystem, content creators amplify prejudice, erode social cohesion, and perpetuate cycles of mistrust and scapegoating. This study highlights the enduring power of antisemitic myths in contemporary digital conflict narratives and calls for further research into the structural mechanisms enabling their spread.
