Quisling was put on trial during the legal purge in Norway after World War II. He was found guilty of charges including embezzlement, murder and high treason against the Norwegian state, and was sentenced to death. He was executed by firing squad at Akershus Fortress, Oslo, on 24 October 1945. The word "quisling" became a byword for "collaborator" or "traitor" in several languages, reflecting the contempt with which Quisling's conduct has been regarded, both at the time and since his death.
