The KUD was organized on a national, state, and local level and cooperated with all institutions concerned with the "German Question": schools, universities, unions, industry, youth organizations, and the media in Germany and internationally. It functioned as an above party lines platform to discuss perspectives of reunification and to organize various campaigns to express the collective desire for unification. Leading members included important ministers of successive governments from all of the main political parties. The work of the KUD focused particularly on Berlin because the organization wanted the West German capital to move from Bonn to Berlin in order to more directly confront the Soviet sphere of influence. The KUD's influence diminished with the advent of Willy Brandt's Ostpolitik in which the two-state status quo was accepted as a fact and basis for a policy of détente in the late 1960s. In 1991 the KUD ceased to exist.
