Legal purge in Norway after World War II
The legal purge in Norway after World War II (Norwegian: Landssvikoppgjøret; lit. 'National treachery Settlement') took place between May 1945 and August 1948 against anyone who was found to have collaborated with the German occupation of the country. Several thousand Norwegians and foreign citizens were tried and convicted for crimes committed in Scandinavia during World War II. However, the scope, legal basis, and fairness of these trials has since been a matter of some debate.
