What qualifies as a political event is a core question for social and historical research. This article argues that the use of temporal structures in narratives of political and social developments contributes significantly to the making and unmaking of events. We show how arguments that draw upon history play a particularly important role in transforming the everyday unfolding of politics into discernable events with a clear time bracket. Through this lens, we investigate the 2016 Brexit referendum as an event that has triggered extensive debates about both Europe’s experiences of the past and political expectations for its future. Conflicting assessments of history are crucial for understanding how and when Brexit became an event of European significance and why it then ceased to be so. This case also enables us to distinguish more clearly between the agent-centered focus on the event itself, and the analytical ex-post assessment as a critical juncture. Methodologically, the article demonstrates the value of a multi-perspective approach for qualitative analyses with a focus on Brexit narratives articulated across several EU countries and the United Kingdom.
