The Treaty of Rome, officially the Treaty establishing the European Economic Community (TEEC), is an international agreement that led to the founding of the European Economic Community (EEC) on 1 January 1958. It was signed on 25 March 1957 by  Belgium, France, Italy, Luxembourg, the Netherlands and West Germany. The word Economic was deleted from the treaty's name by the Maastricht Treaty in 1993, and the treaty was repackaged as the Treaty on the functioning of the European Union on the entry into force of the Treaty of Lisbon in 2009.
