The study introduces lazaretto and frontline war cemeteries in the territory of north-eastern Slovakia, built as a result of the World War I battles. They are a historical phenomenon unparalleled in Slovakia. They are unique mainly in the method of their foundation as well as in high concentration in a relatively small territory. Most of these memorial sites were not completed during the war. Their construction process therefore had to be finished in the interwar period. The newly established Czechoslovak Republic had to deal with this situation due to the commitments resulting from the post-war international peace treaties. The study focuses on the extent to which the Republic succeeded and by what means and procedures, being compiled to a large extent from the knowledge gained from studying primary archival sources, supplemented by known facts, captured in the specialised literature, related to the studied issue.
