The Maastricht Treaty (formally, the Treaty on European Union or TEU) was signed on 7 February 1992 by the members of the European Community in Maastricht, Netherlands.[1] On 9–10 December 1991, the same city hosted the European Council which drafted the treaty.[2] Upon its entry into force on 1 November 1993 during the Delors Commission,[3] it created the European Union and led to the creation of the single European currency, the euro. The Maastricht Treaty has been amended by the treaties of Amsterdam, Nice and Lisbon.
