Birth of the European Community
1957 Capitoline Hill, Rome, Italy
In short
After two world wars, some European politicians thought the best way to avoid new conflicts was to work together. On 25 March 1957, on the Capitoline Hill in Rome, six countries signed the Treaties of Rome: Belgium, France, West Germany, Italy, Luxembourg and the Netherlands. The European Economic Community was born, aiming for a common market with no customs duties between its members, together with a community for atomic energy. Back in 1951 the same six had already pooled their coal and steel.
Why it matters It was the first big step towards the European Union, which has united in peace countries that were once enemies.

The story
From the rubble to reconciliation
In 1945, when the Second World War ended, Europe lay in ruins. Millions of people were dead, cities were destroyed, many factories were idle and hunger was widespread. In less than eighty years France and Germany had gone to war three times. Many people asked how to stop it happening again.
One answer was simple and brave: to tie the European countries together so closely that war between them would become impossible. On 9 May 1950 the French foreign minister Robert Schuman, inspired by the official Jean Monnet, proposed putting the coal and steel production of France and Germany, the materials needed to make weapons, under a common authority. In 1951 six countries signed the treaty: France, West Germany, Italy, Belgium, the Netherlands and Luxembourg. The ECSC had been born, the European Coal and Steel Community.
The next step
The project, however, did not head straight for a political union. In 1954 the French parliament rejected the idea of a common European army, and many people thought the European dream was over. The six countries then decided to start again from the economy, which was more concrete. In June 1955 their foreign ministers met in Messina, in Sicily, and asked the Belgian Paul-Henri Spaak to prepare a plan. After two years of work and negotiations, the plan was ready.
On 25 March 1957, in a rainy Rome, the representatives of the six countries gathered on the Capitoline Hill, in the Hall of the Horatii and Curiatii in the Palazzo dei Conservatori, and signed two treaties. For Italy there were the prime minister Antonio Segni and the foreign minister Gaetano Martino; for Germany Konrad Adenauer; for Belgium Paul-Henri Spaak. The first treaty created the European Economic Community (EEC), that is, a “common market”; the second created Euratom, so that nuclear energy could be used together for peaceful purposes only. The two documents were written in four languages, all equally valid: Dutch, French, German and Italian.
What is a common market?
The common market promised something that seems normal today: goods, workers, services and money could move between the countries without customs duties, that is, without the taxes paid at the border. The six countries promised to remove duties between themselves, to set a common duty towards other countries and to coordinate their economic policies, for example farming. Tariffs between the countries were abolished completely on 1 July 1968, a year and a half ahead of schedule.
The treaties came into force on 1 January 1958. In time the institutions grew: the European Commission, which proposes laws, the Council, which brings together the governments, a parliamentary Assembly, later to become the European Parliament, and a Court of Justice to make sure the rules were followed. Among the fathers of this idea we remember, besides Schuman and Monnet, three Christian Democrat leaders who were convinced of European unity: the Italian Alcide De Gasperi, the German Adenauer and Schuman himself, who all spoke the language of reconciliation.
An open door
The Treaty of Rome was not meant to be a closed club. The text said that any European state could ask to join. The United Kingdom tried as early as the 1960s, but was blocked by the veto of de Gaulle's France; it joined only in 1973, together with Ireland and Denmark. The Community went on growing in the following decades, until it became the great common home of today.
Why it happened
The deepest cause was the desire for peace. After two world wars that began in Europe, many leaders understood that the biggest states must no longer be enemies, but partners in the same business: if wealth and interests are tangled together, war costs everyone too much.
The economy mattered too: European companies needed bigger markets to compete with those of the United States and the Soviet Union, and the countries needed to rebuild fast. Finally, in the climate of the Cold War, Western Europe wanted to be united and strong in the face of the Soviet bloc, with American support through the Marshall Plan.
What changed
The common market worked better than expected, partly because companies could at last sell in an area with about 170 million people. Between 1958 and 1968 trade among the six countries grew much faster than trade with the rest of the world, and the European economy enjoyed a long period of growth. France, Germany and Italy, once enemies, became regular partners.
The Treaty of Rome is the starting point of today's European Union: later treaties have changed and widened it, but the idea of a market without borders and of common institutions has remained. From it came the single market, free movement of people, the Erasmus programme for studying abroad and, many years later, the single currency.
The road has not been a straight one: there have been vetoes, crises and heated arguments, and the European project also has many critics. But the basic idea, that common problems are better tackled together, gave Western Europe one of the longest periods of peace in its modern history.
