Josef Terboven, the Reichskommissar of Norway, made a significant move by appointing Vidkun Quisling as the Minister President of the National Government in the occupied territory. This decision occurred within the context of World War II, where Norway had been occupied by German forces since April 1940. Quisling, a former military officer, had previously established himself as a prominent collaborator with the Nazis, advocating for Norwegian policies that aligned with German interests. His appointment was seen as a method to legitimize and formalize the puppet government under direct German supervision, effectively sidelining any remaining Norwegian sovereignty. The collaborationist government aimed to implement measures that would facilitate the German war effort and suppress any resistance movements within Norway.

Quisling’s government faced opposition from various factions within Norway, particularly from the leftist and nationalist movements which resisted German occupation. Despite this, his administration primarily sought to promote policies favorable to Nazi ideology, including anti-Semitic legislation and the repression of dissent. The move was characterized by increased surveillance and the establishment of a loyalist police force that would enforce occupation policies. As World War II progressed, the Quisling government's actions increasingly aligned with Nazi Germany's broader goals, prompting further resentment among the Norwegian populace. The continued collaboration and the nature of Quisling's regime contributed significantly to the legacy of betrayal in Norwegian history, as post-war sentiment largely vilified his actions and governance.

Moreover, Quisling’s government served as a stark reminder of the complex relationships between occupying forces and local collaborators during times of conflict. Even as the Nazis established control, they faced persistent resistance and guerrilla efforts from Norwegians pushing back against the oppressive regime, leading to a turbulent era that would have lasting repercussions after the war. The appointment of Quisling marked a critical juncture in Norway's wartime experience, framing its history of occupation and the aftermath of the conflict, which would see a stiff reckoning with issues of collaboration and loyalty after liberation.
