Why has the European Union struggled to become a strong supranational community?

The European Union (EU) has faced significant challenges in evolving into a robust supranational community, primarily due to the enduring influence of nationalism and the primacy of the nation-state as the focus of citizen loyalty.1

From a communitarian perspective, which emphasizes the importance of shared values and social cohesion, the EU struggles because it lacks a unified cultural or social base comparable to that of a nation-state. Key obstacles include:

• Sovereignty and Nationalism: National governments remain the primary providers of security and social services, reinforcing the state as the center of political life. Attempts at deeper integration often founder when they threaten to limit national sovereignty.1
• Democratic Deficit: The EU is frequently criticized for a democratic deficit, where institutions are perceived as technocratic and distant from ordinary citizens. The European Parliament has historically held less influence than national executive branches, and the lack of direct accountability to constituents hinders the development of a shared European political community.2
• Welfare State Divergence: Democratic legitimacy in Europe is deeply tied to welfare functions. Because these models vary radically across member states, the EU cannot easily centralize these roles to build a common sense of community.2

Ultimately, while the EU has achieved significant economic integration, the persistence of national political cleavages and the absence of a singular, cohesive European identity continue to limit its supranational development.213
