History Department preserves the collections dating from XIV to XX century. The collections are mainly comprised of cards, photographs, decorations, weapon and army equipment, uniforms, flags, books and nonbook materials, archival materials, charters from modern era, stamps and everyday objects. The department also holds a numismatic collection. As the battles and heroes piqued the public interest, the collections grew rich with the belongings of Duke Miloš Obrenović, Prince Đorđe Karađorđević, Master Jovan Obrenović, Field-Marshal Stepa Stepanović, Field-Marshal Petar Bojović, General Kosta Protić, Lieutenant Dragutin Gavrilović and many others.
The founding of the Museum in 1952 realized the idea of establishing the History Department; nevertheless, it was only in the 1966 when the first qualified historian was employed. For decades, collected materials were originally related to Partisan organization or Communist Movement in the Second World War. However, despite the fact that the History Department has collected materials and conserved collections related to all historical periods, most of the collections are still linked to uprisings, wars, soldiers, officers, and military life in general, both in peace and war, during the period from 1804 to 1945.
Social history of Čačak also covers the following themes: legacy of priestly families, head of the municipality, and the Sokol movement; old and rare books collection; as well as the photographs presenting the town life during XX century.
The collections of this department have been continuously and systematically processed and prepared for exhibitions. Due to the historians’ research conducted in archives and libraries, an abundant amount of additional museum material has been collected. Certain museological themes were present in the form of exhibition catalogues, books, and scientific papers and articles. Not only have the History Department curators published their scientific papers in the National Museum Journal frequently, but they also contributed to the work of the Editorial Board. In addition to this, they have published the scientific papers in the most renowned national magazines in the Social science, and organized several conferences in the home institution.
