Vidkun Abraham Lauritz Jonssøn Quisling (/ˈkwɪzlɪŋ/; Norwegian: [ˈʋɪ̂dkʉn ˈkʋɪ̂slɪŋ] ; 18 July 1887 – 24 October 1945) was a Norwegian military officer, politician and Nazi collaborator who headed the government of Norway during the country's occupation by Nazi Germany during World War II.
He first came to international prominence as a close collaborator of the explorer Fridtjof Nansen and through organising humanitarian relief during the Russian famine of 1921 in Povolzhye. He was posted as a Norwegian diplomat to the Soviet Union and for some time also managed British diplomatic affairs there. He returned to Norway in 1929 and served as minister of defence in the agrarian governments of Peder Kolstad (1931–1932) and Jens Hundseid (1932–1933).
