The EEC was setup to integrate further the economies of the European Coal and Steel Community members beyond simply coal and steel. It was very ambitious plan which looked to create a common market in which there would be free movement of capital, goods, people and services.
In 1973, Ireland, the United Kingdom and Denmark joined the EEC.
