The Treaty on European Union was signed at Maastricht on 7 February 1992 and came into force on 1 November 1993. The Union Treaty established the European Union (by Article A). It changed the name of one of the Communities (all three of which continue to exist). Article G made numerous amendments to the EEC Treaty, the first being to replace "European Economic Community" by "European Community" throughout. There are two consequences of this change: a) What used to be Regulations (EEC) N°... are now Regulations (EC) N°... Any instruments adopted on or after 3 November 1993 are so designated; b) References to the EEC Treaty are apposite in historical contexts only. It is now the EC Treaty. The ECSC and Euratom Treaties continue to be so called.
