European Parliament.
The decision to pool the coal and steel industries of six European countries, brought into force by the Treaty of Paris in 1951, marked the first step towards European integration. The Treaties of Rome of 1957 strengthened the foundations of this integration, as well as the notion of a common future for the six European countries involved.

- The Treaty of Paris
Desmond Dinan. In: Oxford Research Encyclopedia of Politics. (Retrieved 6 Jun. 2023)
On June 20, 1950, representatives of six countries (Belgium, France, the Federal Republic of Germany, Italy, Luxembourg, and the Netherlands) met in Paris to launch what became the first intergovernmental conference in the history of European integration. The outcome, after a year of difficult negotiations, was an agreement to establish the European Coal and Steel Community (ECSC), signed in Paris on April 18, 1951. Based on the Schuman Declaration of May 1950, the Paris Treaty established a High Authority of a “supranational character,” with responsibility for managing a common market for two key industrial sectors. The Coal and Steel Community was a political as much as an economic undertaking.
