As a pejorative term, the word “collaboration’ can describe the treason of cooperating with enemy forces occupying one’s country. As such it implies criminal deeds in the service of the occupying power, including complicity with the occupying power in murder, persecutions, pillage, and economic exploitation as well as participation in a puppet government.

The use of “collaboration” to mean “traitorous cooperation with the enemy,” dates from 1940, originally in reference to the Vichy Regime in France, as well as the French civilians who sympathised with Nazi Germany’s doctrine and voluntary troops (LVF) who fought against the Fighting France and later De Gaulle’s French Force. Since then, the words collaboration and collaborateur have this very pejorative meaning in French (the shortened form collabo only has this pejorative and insulting meaning).
