In 1941, in spite of Yugoslav attempts to remain neutral in the war, the Axis powers invaded Yugoslavia. The territory of modern Serbia was divided between Hungary, Bulgaria, the Independent State of Croatia, Greater Albania and Montenegro, while the remaining part of the occupied Serbia was placed under the military administration of Nazi Germany, with Serbian puppet governments led by Milan Aćimović and Milan Nedić assisted by Dimitrije Ljotić's fascist organization Yugoslav National Movement (Zbor).
