On 18 April 1951, six states sign the Treaty establishing the European Coal and Steel Community. The notion of a sectoral community was to be emulated several times. Accordingly, in 1952, a ‘health pool’ and a ‘transport pool’ came to be discussed. The 3 October 1952 edition of the German daily newspaper Stuttgarter Nachrichten takes stock of this.

Among other plans for European union on a sectoral basis, the creation of a single currency is considered in the early 1950s by France, Belgium, Luxembourg, the United Kingdom and the Netherlands.

On 29 December 1952, 300 students, inspired by the initial success of the Schuman Plan, demonstrate in Menton, on the French-Italian border, in favour of European integration.

On 13 June 1950, the Dutch daily newspaper Het Vrije Volk comments on the proposal by Dirk Stikker, Dutch Foreign Minister, to pursue European integration by sector.
