The thesis deals with the history of the Volunteer Fire Department Tolmin in the period from its foundation to the Second World War. This period includes two major systems which have shaped the firefighting in the Tolmin area. The first system was present during the Austro-Hungarian Monarchy and the second was present during the Italian annexation of the Slovene Littoral. The latter befell the Slovenian Littoral after the First World War and is considered a phenomenon of the region. The first chapter deals with the pre-history of the fire department and tries to outline the general and local circumstances present prior to the foundation of the fire department in Tolmin. The second chapter deals with the foundation of the fire department and the reasons which contributed to its establishment. The subchapters discuss the events and highlights that were crucial for the foundation and initial development of the fire department in Tolmin. The next bigger chapter describes the conditions and activities of the fire department on multiple levels. The next chapter describes the period of time between the wars. Here, the emphasis is mainly on the work and interpretations of important sources. The research is based on the archival sources, newspaper articles, interviews with some of the firefighter veterans, the visual materials and the otherwise small amount of literature dealing with the local and general history and the development of firefighting in the Slovenian territory.
