Layered Integration Under Pressure: How Successive Crises Reshaped European Union Institutions

Layered Integration Under Pressure: How Successive Crises Reshaped European Union Institutions.This article examines how the European Union (EU) has responded to four major crisesthe Eurozone crisis, the migration crisis, the COVID-19 pandemic, and the war in Ukraineand how these episodes have reshaped its governance.Drawing on Jean Monnet's perspective that crises drive integration, it investigates how these events tested the EU's resilience and governance mechanisms.It asks whether joint action increased, which institutional actors were empowered, and how treaty constraints were managed.The analysis shows that while supranational coordination deepened in each case, the extent and form of integration varied by policy domain.Core institutions such as the European Commission and the European Central Bank repeatedly gained influence, but their roles were shaped by political sensitivities and functional pressures.Rather than revising the EU's legal framework, crisis responses relied on informal coordination, off-budget instruments, and the creative extension of existing tools.The findings suggest that EU governance evolves through incremental adaptation and institutional layering, producing a flexible but uneven mode of integration under pressure.
