It is undeniable fact that wars produce large-scale violence, change dramatically the every day life of ordinary people and often resulted in genocide and forceful deportation of population from one region into another. In some cases, however, wars can serve as catalyst for producing and transfer of knowledge through field trip expeditions into the regions of military operations.
My paper presents such a case study - it deals with the ethnographic expeditions undertaken by foreign (Czech and German) and Bulgarian scholars in Macedonia during the First World War. These research trips have remained for more than half a century invisible, ignored and forgotten for the scholars and wide public.
