A Contested Union: A Review of Economic, Political, and Cultural Tensions in the Eurozone

Abstract

This paper provides a comprehensive review of academic literatures that concerning the multifaceted impacts of the Economic and Monetary Union (EMU). More than two decades after the circulation of its physical currency, the legacy of the Euro is characterized by a profound duality. It has facilitated unprecedented financial integration while simultaneously creating new conduits for economic divergence and systemic risk. Envisioned as a capstone of political unity, its governance structures have strained national sovereignty and catalyzed a new, structural political cleavage rooted in Euroscepticism. Finally, intended as a unifying symbol, the Euro coexists uneasily with the enduring power of national identities and the collective memory of antecedent currencies. This review synthesizes empirical findings from economics, political science, and sociology to analyze three core tensions: (1) the conflict between the EMU's promise of convergence and the reality of economic divergence, particularly for the small and medium-sized enterprise (SME) sector; (2) the struggle between supranational governance and national sovereignty, which has redefined European political contestation; and (3) the cultural dialectic between a constructed European identity and the persistent legacy of national belonging. The paper concludes that the Euro is not a static endpoint of integration but rather a dynamic and contested arena wherein the foundational contradictions of the European project are continually negotiated and reshaped.
