A look at the evolution of the European Economic Community 20 years after the signing of the Treaty of Rome.
On 25 March 1957, the Treaty of Rome was signed to establish the EEC and the European Atomic Energy Community, providing the framework for what is now known as 'The Community'.
The Community meant a new lease of life for 180 million Europeans. The new organisation would have a European Parliament, Council, Commission and Court of Justice. The initial signatories were Belgium, France, Italy, Luxembourg, the Netherlands and West Germany.
On 1 July 1968, the Customs frontier barriers between the six were done away with to allow for the first time a free exchange of commerce. Interchange multiplied fifteen times between these countries in as many years.
In 1969 negotiations began with four further countries seeking admission to the community - Britain, Ireland, Denmark and Norway. Negotiations between Britain and the six members took a year and were finally signed on 30 June 1970.
This report includes footage of the signatories of the Treaty of Rome, and later the new signatories.
