The Evolution of the European Union

In 1957, the European Economic Community was formed by the signing of the Treaty of Rome by six European nations. Across the next 35 years, six new nations were added to the Community; then, in 1992, the Maastricht Treaty was signed, creating both the European Union that we know today and the four freedoms: movement of goods, services, people and money. Since 1992, the EU has continued to grow and, today, 28 nations have opted to become member states.
