A "Quisling" refers to a person who betrays their own country by collaborating with an enemy, particularly during wartime. The term originates from Vidkun Quisling, a Norwegian politician who collaborated with Nazi Germany during World War II. His actions led to the occupation of Norway and made him synonymous with treachery. The word has since evolved to describe any traitor or collaborator, especially those who assist foreign powers against their own nation. Quislings are often viewed with disdain, as their actions can undermine national sovereignty and loyalty, impacting the lives of many citizens.
