Treaty of Brussels (Merger Treaty)
What was the aim of the Treaty establishing a single Council and a single Commission of the European Communities?
The Brussels Treaty establishing a single Council and single Commission of the European Communities (known as the ‘Merger Treaty’) was signed with the explicit intention of unifying the 3 then-existing European Communities (EC) — the European Coal and Steel Community (ECSC), the European Economic Community (EEC) and the European Atomic Energy Community (EAEC or more commonly known as ‘Euratom’). While keeping the 3 communities legally independent, the Merger Treaty rationalised their institutions by merging their then still independent executive bodies — thus bringing to 5 the number of common European institutions — and amended the 3 community treaties accordingly.
