Brussels and the European Union

Brussels in Belgium is considered the de facto capital of the European Union, having a long history of hosting the institutions of the European Union within its European Quarter. The EU has no official capital, and no plans to declare one, but Brussels hosts the official seats of the European Commission, Council of the European Union, and European Council, as well as a seat (officially the second seat but de facto the most important one) of the European Parliament.

In 1951, the leaders of six European countries (Belgium, Luxembourg, The Netherlands, France, Italy and West Germany) signed the Treaty of Paris which created the European Coal and Steel Community (ECSC), and with this new community came the first institutions: the High Authority, Council of Ministers, Court of Justice and Common Assembly. A number of cities were considered, and Brussels would have been accepted as a compromise, but the Belgian government put all its effort into backing Liège, opposed by all the other members, and was unable to formally back Brussels due to internal instability.

Agreement remained elusive and a seat had to be found before the institutions could begin work, hence Luxembourg was chosen as a provisional seat, though with the Common Assembly in Strasbourg as that was the only city with a large enough hemicycle (the one used by the Council of Europe). This agreement was temporary, and plans were set to relocate the institutions to Saarbrücken which would serve as a "European District", but this did not occur.
