The European Union as a Post-Westphalian Political Order: A Critical Appraisal
Introduction
The Westphalian system, inaugurated by the Peace of Westphalia in 1648, has long been regarded as the foundational framework of modern international relations. It enshrined the principle of state sovereignty, territorial integrity, and non-interference in the internal affairs of states, thereby constructing the modern international order as a system of autonomous nation-states. Against this backdrop, the European Union (EU) is often heralded as a quintessential example of a “post-Westphalian” political order—a political and legal entity that transcends the traditional model of sovereignty by institutionalizing shared governance, pooling authority, and enabling supranational decision-making.
This essay critically examines the claim that the EU represents a post-Westphalian order. It situates the EU within the theoretical debates of sovereignty and integration, analyzes its institutional innovations, and evaluates the extent to which it departs from or remains embedded in the Westphalian paradigm.
The Westphalian System and Its Core Principles
The Westphalian model is characterized by several defining features:
- Sovereign Territoriality – States exercise supreme authority within their borders, free from external interference.
- Legal Equality of States – Regardless of size or power, states are formally equal in international law.
- Non-Intervention Principle – External actors cannot interfere in domestic matters of other states.
- Decentralized Anarchy – The international system lacks a central authority, making cooperation contingent upon intergovernmental consent.
In the Westphalian order, the nation-state is the supreme unit of political authority. Any erosion of these principles, therefore, constitutes a challenge to Westphalian sovereignty.
The European Union as a Post-Westphalian Entity
1. Pooling of Sovereignty
The EU departs from the Westphalian system by encouraging pooling and sharing of sovereignty. Member states voluntarily cede authority to supranational institutions such as the European Commission, European Court of Justice (ECJ), and European Central Bank. The ECJ, for example, has established the principle of supremacy of EU law (Costa v. ENEL, 1964; Van Gend en Loos, 1963), ensuring that EU directives take precedence over conflicting national legislation. This undermines the Westphalian doctrine of absolute sovereignty.
2. Supranational Governance
The EU represents a hybrid of intergovernmentalism and supranationalism. Institutions like the European Parliament exercise legislative powers directly elected by citizens across member states, while the European Central Bank controls monetary policy for the Eurozone, independent of national governments. Such arrangements reflect a multi-level governance model (Marks, Hooghe, 2001), which transcends the state-centric logic of Westphalia.
3. Open Borders and Free Movement
The Schengen Agreement and EU treaties institutionalize free movement of people, goods, services, and capital. This effectively erodes the notion of sovereign territorial borders as impermeable lines of control—a hallmark of the Westphalian system. While states still exercise authority over external borders, the dismantling of internal borders redefines sovereignty as shared and diffused.
4. Foreign and Security Policy
Although foreign policy remains largely intergovernmental, the EU has developed a Common Foreign and Security Policy (CFSP) and the European External Action Service (EEAS), reflecting attempts to project collective sovereignty externally. While this does not displace national prerogatives in defense and diplomacy, it challenges the Westphalian assumption of exclusive state control over external relations.
5. Citizenship and Identity Beyond the Nation-State
The creation of European Union citizenship grants individuals rights and protections transcending national frameworks. Citizens can move, reside, and work freely across member states, vote in European Parliament elections, and claim protection from EU law. This dilutes the Westphalian linkage between sovereignty, territory, and citizenship, creating a post-national political identity (Habermas, 2001).
Theoretical Interpretations of the EU as Post-Westphalian
Liberal Institutionalism and Integration Theory
From the perspective of neofunctionalism (Haas, 1958), the EU embodies the logic of “spillover,” where integration in one sector necessitates integration in others. This gradually displaces national sovereignty in favor of supranational authority, a departure from Westphalia.
Cosmopolitan and Post-National Perspectives
Scholars such as Jürgen Habermas argue that the EU exemplifies post-national democracy, wherein sovereignty is reconstituted beyond the nation-state. Similarly, David Held’s cosmopolitanism views the EU as a prototype for global governance structures that transcend territorial exclusivity.
Realist Critiques
Conversely, realist scholars argue that the EU remains embedded in the Westphalian order. Member states retain ultimate control over security and defense (NATO remains primary), and the possibility of Brexit illustrates the reversibility of sovereignty pooling. From this perspective, the EU is an advanced form of intergovernmental cooperation, not a post-Westphalian revolution.
Limits to the Post-Westphalian Thesis
1. Persistence of State Sovereignty
Despite supranational elements, member states remain the masters of the treaties. They control treaty reform, budgetary contributions, and can unilaterally exit the Union (as demonstrated by Brexit). This underscores the enduring relevance of Westphalian sovereignty.
2. Uneven Integration
While monetary policy in the Eurozone exemplifies sovereignty pooling, fiscal policy remains under national control. Similarly, security and defense remain predominantly intergovernmental. The EU thus represents a partial erosion rather than a wholesale abandonment of Westphalia.
3. Crises of Integration
The Eurozone crisis, migration crisis, and Brexit illustrate the fragility of supranational arrangements. These crises reveal the resilience of national identity, democratic accountability, and territorial control, challenging the notion of a post-Westphalian order.
Critical Evaluation
The EU undoubtedly departs from the Westphalian model by establishing supranational institutions, eroding territorial borders, and creating a post-national identity. However, it does not fully supplant the Westphalian logic. Instead, the EU embodies a hybrid order:
- It transcends Westphalia by institutionalizing multi-level governance, shared sovereignty, and supranational law.
- It remains tied to Westphalia because states retain ultimate authority, particularly in fiscal policy, security, and treaty-making.
Thus, the EU should not be viewed as a wholly post-Westphalian entity, but rather as a neo-Westphalian order—a system in which sovereignty is reconstituted, diffused, and shared without being eliminated.
Conclusion
The European Union represents the most advanced experiment in post-Westphalian governance, but its reality is more complex than the rhetoric suggests. It transcends Westphalia by pooling sovereignty, creating supranational law, and fostering a post-national identity, yet it remains embedded in state consent and intergovernmentalism.
Rather than signifying the death of Westphalia, the EU demonstrates its transformation: sovereignty is no longer absolute and indivisible but is increasingly relational, conditional, and layered. The EU thus represents not the end of the Westphalian order but the emergence of a post-sovereign political space, foreshadowing new possibilities for governance in a globalized world.

| Realist Critique | Member states retain ultimate authority; Brexit demonstrates reversibility of pooled sovereignty. | Suggests EU remains embedded in Westphalian logic; post-Westphalian character is partial. |
| Limits of Post-Westphalian Thesis | Persistence of state sovereignty, uneven integration (fiscal, defense), crises of integration. | EU exemplifies hybrid order: neo-Westphalian or layered sovereignty rather than full post-Westphalian system. |
