After getting a legal status UEF campaigned for the European Federal Pact. It consisted of an attempt to transform the Advisory Assembly of the Council of Europe into the Constituent Assembly of the European Federation. The fundamental tool was a petition, signed by thousands of citizens across Europe and a large number of eminent people in political, intellectual and scientific life, which asked the Advisory Assembly to draw up a text for a federal pact, and recommend its ratification to the member states of the Council of Europe. UEF also campaigned for the ratification of the European Defence Community and for the establishment of a political community.
