The Hallstein Commission held office for two mandates, from 7 January 1958 to 30 June 1967. This was the EEC’s very first Commission and, as such, it prepared the ground for the Common Market and the Common Agriculture Policy (1962). It overcame the institutional crisis in the 1960s and succeeded in setting up an efficient administrative system, enabling the expansion of the European institutions to third countries and gaining the trust of numerous investors.
