Transformative securitization: Rethinking the Copenhagen School in light of COVID-19, climate change, and the war in Ukraine

This article advances securitization theory by introducing the concept of transformative securitization, in which crises are not only framed as existential threats but also as catalysts for reconstituting political orders. Drawing on the Copenhagen School and Hannah Arendt’s notion of natality, the article distinguishes transformative securitization from conservative forms that aim to preserve the status quo. It conceptualizes transformative securitization through three dimensions: agency (bottom-up and participatory), procedure (disruptive yet potentially democratizing), and outcome (yielding durable institutional or normative change). Through empirical illustrations from Denmark and Norway’s responses to COVID-19, Russia’s invasion of Ukraine, and climate change, the article shows how securitization can both constrain and enable democratic transformation. It finds that while some responses reinforce executive power and narrow deliberative space, others—especially in climate politics—reflect participatory and future-oriented securitizing moves that can reconfigure societal sectors or entire polities. Climate change emerges as a paradigmatic case of transformative securitization, where intergenerational justice and systemic change are driven by civic agency. By bridging crisis and political founding, the concept refines securitization theory’s understanding of extraordinary politics and offers new tools to analyze the democratic potential and pitfalls of security responses in an era of overlapping, urgent predicaments.
