The Congress of European Federalists for the European Political Community met in Wiesbaden from January 9 to 11, 1959.

After the ceremonial opening of the conference by the President of the Commission of the European Economic Community, Walter Hallstein, and the welcoming addresses by prominent participants such as Robert Schuman and Jean Monnet, the fundamental issues of European unity were discussed in a first plenary session.

This was followed on the evening of the first day by an international forum in which representatives from Western European countries publicly discussed the future of Europe. On Saturday, three commissions met to discuss urgent common tasks, the foundations of a political statute and the propagation of European policy. In the afternoon, the annual meeting of the Action of European Federalists took place. The conference participants used their free evening to visit numerous cultural events in the spa town. On the final day, the results of the commissions were first discussed in plenary.

The resolutions were followed by a dinner in the Great Hall of the Kurhaus, hosted by the Hessian state government and the municipal authorities. Prince Bernhard of the Netherlands, the President of the European Parliament Robert Schuman and the German Foreign Minister Heinrich von Brentano, among others, signed the city's Golden Book.
