The Treaty of Rome, or EEC Treaty (officially the Treaty establishing the European Economic Community), brought about the creation of the European Economic Community (EEC), the best known of the European Communities (EC). The treaty was signed on 25 March 1957 by Belgium, France, Italy, Luxembourg, the Netherlands and West Germany, and it came into force on 1 January 1958. Originally the "Treaty establishing the European Economic Community", and now continuing under the name "Treaty on the Functioning of the European Union", it remains one of the two most important treaties in what is now the European Union (EU).
The treaty proposed the progressive reduction of customs duties and the establishment of a customs union. It proposed to create a single market for goods, labour, services, and capital across member states. It also proposed the creation of a Common Agriculture Policy, a Common Transport Policy and a European Social Fund and established the European Commission.
The treaty has been amended on several occasions since 1957. The Maastricht Treaty of 1992 removed the word "economic" from the Treaty of Rome's official title, and in 2009, the Treaty of Lisbon renamed it the "Treaty on the Functioning of the European Union".
In 1951, the Treaty of Paris was signed, creating the European Coal and Steel Community (ECSC). The Treaty of Paris was an international treaty based on international law, designed to help reconstruct the economies of the European continent, prevent war in Europe and ensure a lasting peace.
The original idea was conceived by Jean Monnet, a senior French civil servant and it was announced by Robert Schuman, the French Foreign Minister, in a declaration on 9 May 1950. The aim was to pool Franco-West German coal and steel production, because the two raw materials were the basis of the industry (including war industry) and power of the two countries. The proposed plan was that Franco-West German coal and steel production would be placed under a common High Authority within the framework of an organisation that would be open for participation to other European countries.
