Vidkun Quisling, traitor. The man who surrendered his country to Hitler and the Nazis. The man who sought to acquire power to serve his own interests, and those of the Germans, leaving his own country and culture behind.
When Germany invaded Norway in 1940, Quisling was standing by to take control. When the Nygaardsvold government retreated, Quisling attempted a coup d'etat. During a news broadcast, he announced the members of his new government, and encouraged the Norwegian people to surrender and support the German occupation.
In spite of having the support of Hitler, Quisling was denied the title of Minister President until 1942.
After the war, Quisling was prosecuted, found guilty, and finally executed by shooting.
Ever since, the name Quisling has been synonymous with traitor.
