Independent of each other, though contemporaneous, the Anglo-American occupiers of Germany and the newly founded United Nations Educational, Cultural and Scientific Organization employed culture to foster greater intercultural and international understanding in 1945. Both enterprises separately saw culture as offering a means of securing the peace in the long term. This article compares the stated intentions and activities of the Anglo-American occupiers and UNESCO vis-à-vis transforming morals and public opinion in Germany for the better after World War II. It reconceptualizes the mobilization of culture to transform Germany through engaging theories of cultural diplomacy and propaganda. It argues that rather than merely engaging in propaganda in the negative sense, elements of these efforts can also be viewed as propaganda in the earlier, morally neutral sense of the term, despite the fact that clear geopolitical aims lay at the heart of the cultural activities of both the occupiers and UNESCO.
