Abstract
<jats:p>During World War I, the territory of the Kingdom of Serbia was divided into two occupation zones: the central and western parts were occupied by the Austro-Hungarians, while the eastern and southern parts were annexed to Bulgaria. The occupation apparatuses had a distinctly repressive character. Particularly in the territories under Bulgarian occupation, war crimes were committed, and a policy of Bulgarization of the Serbian population was implemented. At the end of the war, the state authorities of the Kingdom, and later the Kingdom of Serbs, Croats and Slovenes, raised the issue of punishing foreign war criminals, but also “domestic collaborators”, that is, subjects who collaborated with the occupiers or had some benefit from the occupation. The article analyzes the issue of punishing “collaborators with the occupier” in the territory of the former Kingdom of Serbia, based on existing literature and previously unused material from the Ministry of Justice of the Kingdom of Serbs, Croats and Slovenes.</jats:p>
