The European Union adopted 9 May as "Europe Day" at the Milan summit in 1985 to celebrate that Robert Schuman presented his proposal on the creation of an organised Europe, indispensable to the maintenance of peaceful relations, on 9 May 1950. This proposal, known as the Schuman declaration, is considered by many to be the beginning of the creation of what is now the European Union.
