Notes on What Is the European Union?

The EU is a unique political arrangement, neither a conventional international organization nor a simple regional bloc.
It can be conceptualized in five ways: as an international organization, a regional integration association, a political system, a unique entity, or a combination of these.
Theories mainly explain: how the EU evolved (e.g., neofunctionalism, intergovernmentalism from IR scholars) and what it has become (e.g., a political system, multilevel governance from comparative politics).
The EU is debated as an "actor" or sui generis (unique) because it's more than an IO but less than a superstate. No single theoretical framework is universally accepted.

A state is a legal-physical entity with authority over a fixed, populated territory, legally and politically independent, and recognized by its people and other states. Citizenship and national identity are linked to state sovereignty and borders.
The Peace of Westphalia (1648) established modern state sovereignty.
The EU challenges state-centric thinking by pooling authority in specific areas while preserving member states' individual sovereignty.

International organizations (IOs) emerged after 1945 to address transnational problems through voluntary cooperation.
IOs do not typically impose rulings but promote coordination. Their numbers grew significantly:
- Fewer than 220 in 1909 to over 70{,}000 today.
Categories:
- Intergovernmental organizations (IGOs): national government representatives (e.g., UN).
- International nongovernmental organizations (INGOs or NGOs): individuals or private associations.
Integration through IOs involves states pooling authority in selected areas, creating shared institutions with restricted powers. Full political union is the ultimate, controversial aspiration for some in the EU context.
Regional integration is closely tied to sovereignty pooling and transferring authority.

The primary motive for European integration after 1945 was peace.
Federalists (from 1946) advocated a European federation; the Council of Europe (1948) was an early step.
Mitrany's functionalism proposed binding states through international agencies in specific domains, where functional ties would lead to political ties and gradually reduce state sovereignty.
Neofunctionalists (Haas, Lindberg) adapted functionalism to the EU, emphasizing "spillover": integration in one area necessitates integration in others, leading to deeper cooperation. Haas highlighted an "expansive logic"; Lindberg, a "chain-reaction" of integration. This contrasted with realist IR theory's state-centric view.
Regional integration stages:
1. Free trade area: Eliminates internal trade barriers (e.g., EEC in 1960s, NAFTA/USMCA).
2. Customs union: Adds a common external tariff (e.g., EEC in 1968).
3. Single market: Allows free movement of goods, services, capital, and people (largely by early 1990s).
4. Economic and social policy coordination: Harmonizes policies on education, employment, healthcare, and monetary policies, leading to a common currency for members.
5. Political integration: Greater coordination in foreign/defense policy, potentially leading to a federal union (controversial).

Ben Rosamond proposed five ways to study the EU, including viewing it as an international organization, a regionalism example, a policy-making dynamic, a unique organization, or, critically, a political system in its own right (underpinning multilevel governance).
The EU's complexity makes traditional classification difficult, leading to a focus on its executive, legislative, and judicial features, citizen engagement, and power dynamics between EU institutions and member states.
The EU is widely seen as a distinct political organization with layered authority and shared competencies.

Integration involves surrendering or pooling state sovereignty, often restricted to specific policy areas.
Regional institutions coordinate rule-making, but member states primarily enforce them, facing fines or pressure for non-compliance.
This process raises questions about national autonomy versus regional governance.

EU studies lack a single theoretical framework.
The EU has executive, legislative, and judicial components, with governance involving elections, referendums, and interest groups.
The debate over moving towards full political union continues, with proponents citing peace and stability, and opponents fearing loss of sovereignty and democratic legitimacy.
