The Treaty of Brussels.
The Common Market, officially known as the European Economic Community (EEC), was founded on March 25, 1957, with the signing of the Treaty of Rome. It aimed to create a common market and promote economic integration among its founding members: Belgium, France, Germany, Italy, Luxembourg, and the Netherlands. The EEC later evolved into the European Union (EU) with the Maastricht Treaty in 1993.
France joined the EEC in 1957 (began functions in 1958), and was a signatory to the Maastricht Treaty that established the EU in 1993.
Portugal was recognized by the Treaty of Zamora as an independent kingdom in 1143.
The EU traces its origins from the European Coal and Steel Community (ECSC) and the European Economic Community (EEC) formed by six countries in 1958. In the intervening years the EU has grown in size by the accession of new member states, and in power by the addition of policy areas to its remit. The Maastricht Treaty established the European Union under its current name in 1993.[8] The last amendment to the constitutional basis of the EU, the Treaty of Lisbon, came into force in 2009.
Poland is already the member of EU since 2004. Both EU and Poland seem to be happy about that.
The European Union is comprised of what was formally the European Coal and Steel Community (founded 1951). In 1993, the Maastricht Treaty created the European Union as we know it today.
