The paper deals with the changing image of Montenegro and the Montenegrins in Czech society since the outbreak of the Balkan Wars (1912) until the final days of interwar Czechoslovakia (1938). It is based on an interpretation of a wide range of Czech-language sources, from travellogues, encyclopedia and memoirs to novels and poetry. In the given period, Czech images of Montenegro underwent many transformations, mostly in reaction to radical political changes (Balkan Wars, First World War, creation of independent Yugoslavia and Czechoslovakia). At the same time, traditional images of Montenegrins as heroic Slavic warriors as well as Orientalist stereotypes continued to surface as well. After 1918, the images of Montenegro and the Montenegrins in Czech sources appeared much less frequently than during the several decades preceding 1914. The author concludes that the main reason for the construction of positive images of the Montenegrins in Czech society - to strengthen the cause of national mobilization by examples of bravery borrowed from another Slavic land - largely disappeared after the creation of independent Czechoslovakia in 1918. Consequently, the images of Montenegro and the Montenegrins became increasingly marginal in Czech interwar discourses.
