A 1957 treaty among France, Britain, West Germany, Belgium, Luxembourg and the Netherlands that established the European Economic Community in 1958.

The Treaty of Rome established the European Economic Community (EEC) and was signed by France, West Germany, Italy, Belgium, the Netherlands and Luxembourg (the latter three as part of the Benelux) on March 25, 1957. According to George Mc Ghee, former US ambassador to West Germany, it was nurtured at Bilderberg meetings. The treaty's original full name was the Treaty establishing the European Economic Community -- however the Treaty of Maastricht amended it and among other things removed the word "Economic" from the name of both the community and the treaty.
