During a first European conference of 'activistic European forces' held in Vienna from 08 to 09/1959 the Federalistic International (FI) was founded. A 'European office' was elected with the task to elaborate the programme of this new political force, which was to pave the way to the 'unification and inner renewal of Europe and the peaceful liberation of Eastern Europe'. From 30/04 to 01/05/1970 a second European conference took place in Zurich and in a series of meetings of the 'European Office' during the following years, the political program of the FI was defined, including the discussions around the name and symbol of the federalist party. The activities of the party diminuished in the middle of the 1980's.
