Treaty establishing the European Economic Community

Treaty establishing the European Economic Community. Signed on 25 March 1957 in Rome, this foundational agreement created the European Economic Community (EEC) among the six nations of the European Coal and Steel Community. Often called the Treaty of Rome, it aimed to establish a common market and progressively harmonize economic policies to foster prosperity and "ever closer union." The treaty entered into force on 1 January 1958, laying the institutional and legal bedrock for what would evolve into the modern European Union.

Background and historical context

The treaty emerged from the post-World War II drive for European integration, championed by statesmen like Robert Schuman and Jean Monnet. The success of the 1951 Treaty of Paris, which created the European Coal and Steel Community, demonstrated functional cooperation. Following the failure of the European Defence Community in 1954, efforts refocused on economic integration. The pivotal Messina Conference in 1955 tasked a committee chaired by Paul-Henri Spaak with drafting plans, leading to negotiations in Val Duchesse and final signing in the Palazzo dei Conservatori on the Capitoline Hill.

Main provisions and key principles

The treaty's core objective was establishing a **common market** through the "Four Freedoms": free movement of goods, capital, services, and people. It mandated a customs union with a common external tariff and prohibited internal tariffs and quotas. Key policies included a Common Agricultural Policy (CAP), rules on competition law to prevent cartels, and provisions for transport policy. The treaty also outlined aims for closer coordination in social and economic policy, seeking balanced trade and improved living conditions across member states like France and West Germany.

Institutional framework and decision-making

The treaty established four main institutions to govern the EEC. The European Commission was created as an independent executive, tasked with proposing legislation and upholding treaty rules. A Council of Ministers, representing national governments, held the primary legislative and decision-making power. The European Parliamentary Assembly (later the European Parliament) was instituted as a consultative body, while the European Court of Justice (ECJ) was empowered to ensure uniform interpretation of European Community law. Key decisions often required a qualified majority voting in the Council.

Amendments and subsequent treaties

The treaty has been substantially amended by several major agreements. The Merger Treaty (1965) consolidated the executives of the EEC, Euratom, and the ECSC. The Single European Act (1986) introduced reforms to complete the single market. Most profoundly, the Maastricht Treaty (1992) established the European Union and created the European Community pillar, while the Treaty of Amsterdam (1997) and Treaty of Nice (2001) prepared for eastern enlargement. Its core provisions were ultimately codified into the Treaty on the Functioning of the European Union via the Treaty of Lisbon (2007).

Impact and legacy

The treaty successfully transformed the economic landscape of Western Europe, fueling decades of growth and integration that helped reconcile historic rivals like France and Germany. Its legal framework, particularly rulings by the European Court of Justice such as in Van Gend en Loos v Nederlandse Administratie der Belastingen, established the principles of direct effect and supremacy of European Union law. The common market evolved into the European Single Market, and the EEC's political ambition paved the way for the European Union, influencing global trade blocs like Mercosur and the African Union. Its signing date, 25 March, is commemorated as Europe Day in some member states.
