The Declaration said that the ECSC marked the birth of the Europe as a political, economic and social entity, reflecting the principles that Robert Schuman had announced in the Schuman Declaration of 1950. It included the statement:
"By the signature of this Treaty, the involved parties give proof of their determination to create the first supranational institution and that thus they are laying the true foundation of an organised Europe. This Europe remains open to all European countries that have freedom of choice. We profoundly hope that other countries will join us in our common endeavour."[1]
