Treaty on European Union

The Treaty on European Union (2007) is one of the primary Treaties of the European Union, alongside the Treaty on the Functioning of the European Union (TFEU). The TEU forms the basis of EU law, by setting out general principles of the EU's purpose, the governance of its central institutions (such as the Commission, Parliament, and Council), as well as the rules on external, foreign and security policy. While the current version of the TEU entered into force in 2009, following the Treaty of Lisbon (2007), the older form of the same document was implemented by the Treaty of Maastricht (1992). After the preamble the consolidated treaty text is divided into six parts.
