European Economic Community
The European Economic Community (EEC) was a regional organization created by the Treaty of Rome of 1957  aiming to foster economic integration among its member states. It was subsequently renamed the European Community (EC) upon becoming integrated into the first pillar of the newly formed European Union in 1993. In 2009, the EC formally ceased to exist and its institutions were directly absorbed by the EU. This made the European Union the formal successor institution of the Community.
- Today this largely rewritten treaty continues in force as the Treaty on the functioning of the European Union, as renamed by the Lisbon Treaty.
