This article examines how German online news media, specifically the Twitter account of Frankfurter Allgemeine Zeitung (@FAZ_NET), engage with historical memory in their coverage of Russian war against Ukraine. Situated within the COMETE Europe project and based on a transnational corpus of tweets from six European countries, the study applies a Foucauldian framework to understand Twitter as a discursive dispositif that shapes public perception through memory-laden narratives. Drawing on cultural memory theory and media discourse analysis, the research focuses on four key timeframes: the war’s outbreak, the Bucha massacre, World War II Victory Day commemorations, and the first anniversary of the invasion. The article reveals that references to the Soviet Union, Nazi Germany, and German-Russian historical relations play a central role in shaping contemporary political narratives. Through a mixed-methods approach combining data analytics with hermeneutic close reading, the study highlights how Twitter enables both institutional and individual actors to produce, disseminate, and contest historical analogies and moral judgments. It argues that the digital mediation of history through social media platforms such as Twitter intensifies the politicisation of memory and underlines the platform’s role in constructing public knowledge and shaping discourse on geopolitical conflict.
