History of EU fondation

The ECSC (European Coal and Steel Community), born of Robert Schuman’s Declaration of 9 May 1950, did not really see the light of day until three years later, with the opening of the common market in coal among the Six, followed by the common market in steel. This happened 17 years ago. What has become of those promises of a ‘pool’, which Jean Monnet was entrusted to create at the time? Have the objectives laid down in the Treaty of Paris been attained?
