Main steps in the ( legal ) Integration of Europe

After the second world war, the idea of a peaceful Europe has been developped.
It´s the birth of a united Europe. It´s main goal was to guarantee peace, improove the economic situations of the States and the political ones between the States. On the 9 May 1950 The ‘Schuman Declaration’ (which proposed that European integration could ensure peace in Europe through the implementation of the ‘Monnet method’) has been presented by the french foreign minister Robert Schumann.
One year later on the 18th april 1951 the treaty of Paris established the European Coal and Steel Community. ( duration for 50 years / ended in 2003 )
This community should should stop States for example to be able to built weapons all by themselves. ( France , West Germany, Italy, Belgium, Luxembourg, Netherlands).

On the 25 March 1957, The Rome Treaties(e.i.f. 1 Jan 1958) were signed by the same 6 „founding States. It created two main Communities
• European Economic Community (EEC)
Communauté économique européenne (CEE)
Europäische Wirtschaftsgemeinschaft (EWG)
• European Atomic Energy Community (EAEC)
Communauté européenne de l'énergie atomique (CEEA)
EuropäischeAtomgemeinschaft

In 1965 the Merger Treaty had been signed in Brussels. It was a combining Treaty because it combined the executive bodies of the European Coal and Steel Community and European Atomic Energy Community and the European Economic Community into a single institutional structure. The german expression for this treaty „ fusionsvertrag“ underlines it´s combining character.
The signatories of this treaty are again the 6 founder States.
