quisling

A quisling is a traitor, especially one who collaborates with an enemy occupying force for personal gain.

The term arose because in World War II, Vidkun Quisling, a Norwegian politician, volunteered to help the occupying Nazis rule Norway for Germany. Quisling was tried for treason and executed at the end of the war, and his name became synonymous with traitor and collaborator. The word quisling is not commonly used in the United States, however, probably because the American term for a traitor is "Benedict Arnold," the name of a Revolutionary War turncoat.
