Treaty of Rome (EEC) 

Treaty establishing the European Economic Community

Two treaties were signed on 25 March 1957 - the Treaty establishing the European Economic Community (EEC) and the Treaty establishing the European Atomic Energy Community (EAEC or Euratom). For both new Communities, decisions were taken by the Council on a proposal from the Commission. The Parliamentary Assembly is to be consulted, and give its opinions to the Council. The Assembly increases in size to 142 members. The European Parliamentary Assembly held its first session the following year, on 19 March 1958. With the Treaties of Rome, a specific provision is made for members to be directly elected (this was implemented in 1979).

  • Signed in: Rome (Italy) 25 March 1957
