Historically, crises have been lauded for fostering European Union (EU) integration. Conversely, it has recently been predicted that the current ‘polycrisis’ will precipitate the EU's demise. However, this dichotomous perspective on crises is oversimplified. In this research note, we argue that a critical‐constructivist approach to norm contestation is uniquely placed to illuminate the shades of grey populating the continuum between these two extremes. As contestation effects may occur on both normative and institutional levels, a norm contestation approach has the potential to open the black box of crises by investigating the prerequisites, actors and processes of crisis and reminding us that these stages are linked in a circular way. Therefore, we argue that a conversation between EU studies and critical‐constructivist norm contestation research is crucial to advancing our understanding of the myriad effects crises have on the EU beyond the dichotomous distinction between integration and demise.
