On 6 April 1941, Axis forces invaded the Kingdom of Yugoslavia. The Royal Yugoslav Army was quickly defeated and Belgrade was captured by 12 April. The country was then occupied and dismembered, with the Wehrmacht establishing the Territory of the Military Commander in Serbia under a government of military occupation. The territory included most of Serbia proper, with the addition of the northern part of Kosovo (centred on Kosovska Mitrovica), and the Banat. It was the only area of partitioned Yugoslavia in which the German occupants established a military government. This was done to exploit the key rail and riverine transport routes that passed through it, and due to its valuable resources, particularly non-ferrous metals. The Military Commander in Serbia appointed Serbian puppet governments to "carry on administrative chores under German direction and supervision". On 29 August 1941, the Germans appointed the Government of National Salvation (, Влада Националног Спаса) under General Milan Nedić, to replace the short-lived Commissioner Administration. A pre-war politician who was known to have pro-Axis leanings, Nedić was selected because the Germans believed his fierce anti-Communism and military experience could be used to quell an armed uprising in the Serbian region of Šumadija.
