In July 1941, a full-scale rebellion by the communist Yugoslav Partisans and the royalist Chetniks erupted in the territory. The Germans pressured Milan Nedić's collaborationist government to deal with the uprisings under the threat of letting the armed forces of the Independent State of Croatia, Hungary, and Bulgaria occupy the territory and maintain peace and order in it. It was absorbed in the Waffen-SS in 1944 after evacuating to Slovenia, and in 1945 was rechristened the Serbian SS Corps (Serbian: Српски СС Kорпус / Srpski SS Korpus; German: Serbisches SS Korps) [2]
