Treaty of Rome (EEC) (1957) — Treaty Brief

Overview

The Treaty of Rome, signed in 1957, established the European Economic Community (EEC), marking a foundational step toward European integration. Its primary aim was to create a common market among its member states by eliminating trade barriers, establishing a customs union, and promoting the free movement of goods, services, capital, and labor. The treaty also laid the groundwork for common policies in sectors such as agriculture and transport and created key institutions, including the European Commission, the Council of Ministers, the European Parliament, and the European Court of Justice. By fostering economic cooperation, the Treaty of Rome sought to enhance economic growth, stability, and political unity in post-war Europe.

Key Obligations

Establishment of a Customs Union: Member states agreed to eliminate customs duties and quantitative restrictions on imports and exports among themselves and to adopt a common external tariff on goods entering the community (Article 9-12).
Free Movement of Goods: The treaty mandates the removal of internal trade barriers, facilitating the free circulation of goods within the EEC (Article 28-30).
Common Agricultural Policy (CAP): Member states committed to a unified agricultural policy aimed at stabilizing markets, ensuring food security, and supporting farmers (Articles 38-43).
Free Movement of Workers: The treaty guarantees the right of workers to move freely between member states for employment purposes (Article 48).
Common Transport Policy: Establishing coordinated transport policies to improve infrastructure and services across member states (Article 74-84).
Harmonization of Economic Policies: Member states are obliged to coordinate economic and monetary policies to ensure balanced development (Article 103-109).
Institutional Framework: Member states must participate in and respect the decisions of the EEC’s institutions, including the European Commission, Council, Parliament, and Court of Justice (Articles 155-189).

Signatories and Status

The Treaty of Rome was originally signed by six Western European countries: Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany. These founding members were motivated by a shared interest in economic recovery and political stability after World War II. Notably, the United Kingdom, a major European economy, did not join the EEC at its inception, opting instead for alternative arrangements; it would only accede to the community later in 1973. Other European countries, such as Norway and Switzerland, also chose not to join the EEC initially, reflecting divergent national interests and concerns over sovereignty.

Since its signing, the treaty has been amended and expanded through subsequent treaties to accommodate enlargements and deepen integration. The original Treaty of Rome remains a core legal foundation of what evolved into the European Union (EU), though its provisions have been subsumed and modified by later treaties such as Maastricht (1992) and Lisbon (2007).

Major Controversies

Sovereignty vs. Integration: A perennial tension has existed between member states’ desire to retain national sovereignty and the treaty’s push for supranational governance. Debates over the scope of Community competences and the authority of EEC institutions have led to political disputes, particularly regarding economic policy coordination and judicial rulings by the European Court of Justice.
Common Agricultural Policy (CAP): The CAP has been a source of controversy due to its budgetary cost, market distortions, and unequal benefits among member states. Critics argue that it disproportionately favors larger agricultural producers and leads to overproduction, while supporters highlight its role in stabilizing food supplies and rural economies.
Enforcement and Compliance: Ensuring uniform application of treaty obligations has sometimes been challenging. Some member states have been slow or reluctant to implement EEC regulations fully, leading to infringement proceedings before the European Court of Justice.
Enlargement and Integration Depth: The treaty’s framework has been tested by successive enlargements, which introduced new members with diverse economic conditions and political priorities. This has raised questions about the treaty’s flexibility and the capacity of EEC institutions to manage a larger and more heterogeneous membership.
Withdrawal and Treaty Exit: Although the original Treaty of Rome did not explicitly provide for withdrawal, the later Treaty on European Union (Maastricht) and the Lisbon Treaty clarified exit procedures. The United Kingdom’s 2016 Brexit referendum and subsequent withdrawal highlighted the complexities and political ramifications of leaving the community founded by the Treaty of Rome.

Recent Developments

While the Treaty of Rome itself remains a historical document, its legacy continues through the EU’s legal framework. In the past five years, the EU has faced challenges that indirectly relate to the treaty’s principles, such as debates over the single market’s future post-Brexit, tensions over rule of law and compliance with EU law by some member states, and efforts to deepen economic integration through initiatives like the European Green Deal and digital market strategies. These developments underscore the ongoing relevance of the treaty’s foundational commitments to economic cooperation and regulatory harmonization.

Why It Matters Now

The Treaty of Rome remains a cornerstone of European integration, underpinning the EU’s single market and institutional architecture. Understanding its provisions and legacy is essential for grasping current debates on European unity, economic governance, and the balance between national sovereignty and supranational authority. For policymakers, scholars, and international delegates, the treaty offers critical insights into the origins and evolution of one of the world’s most significant regional organizations.
