In this book, leading commentators explore the new concept of ‘crisis governance constitutionalism’ in order to better understand how the EU is changed by times of crisis management. European integration has become controversial due to the many crises: Brexit, the pandemic, migrations, energy crisis, the Ukraine war. Drawing on historical resources, the collection’s expert essays show that rather than offer something completely new, crisis governance constitutionalism coexists with long-established constitutionalist narratives of EU integration.
