1957-1973

From the Six to the Nine

The year 1957 saw the advent of a pivotal project in the history of European integration: the creation by the Six of a European Economic Community, which would soon cover the main sectors of economic life. But the ultimate goal of this undertaking was much larger, aiming as it did to 'lay the foundations of an ever closer union among the peoples of Europe', as stated in the preamble to the EEC Treaty. Despite the institutional crisis of 1965 – which helped to water down the supranational character of the EEC – the establishment of the common market went ahead without any upsets and immediately produced remarkable levels of economic performance. These early years also saw the birth of common policies in the areas of agriculture, transport, foreign trade and regional cohesion. The success of this integration persuaded some countries that had previously kept their distance to join the European Communities. On 1 January 1973, these Communities gained three new members: the United Kingdom, Ireland and Denmark.
