Collaborationist Czechism took over a Reich legend about the Third Reich´s fight for Europe of everlasting peace and social reconciliation in the so-called civil war. After the triumph of the Nazi Germany, the Czech issue would have been to be solved. However, during the war intermezzo the Nazi propaganda pretended an interest in the Czech "folk culture" and its apparent creator - the Czech farmer. Simultaneously, the Protectorate promoted the German "folk culture" (mainly the national costume) and the Reich ethnography (e.g. the ethnographer Kerkman, an expert in folk costumes) as unbeatable models for the Czech ethnography. The study describes the resources of the Nazi interest in the "folk culture", the forms of the culture ́s promotion, as well as the causes of an alleged support to the ethnographic curiosities in the Protectorate. However, the "folk culture" and the ethnography that promoted this culture, worked as a support to Czechism, a Czech nation ́s anchor in its alleged roots, and as an expression of national nostalgia and sentiment. The folk costumes and traditions were revitalized. In comparison to the interwar trends of ethnography, both models of the interest in the "folk culture" gave an impression of a kind of anachronism. The models disparaged the Czech and Moravian people down to the position of an ethnographic group. The "folk culture" (especially folk costumes, folk songs) was also used by the exile propaganda around Edvard Beneš, President of Czechoslovakia, to encourage the exile Czechism, to induce a feeling of the Czech nation´s wholeness (in emigration and at home), and to manifest Czechism and Czechoslovakism in the public.
