Joseph Darnand was a French collaborator with Nazi Germany during World War II. A decorated soldier in the French Army of World War I and early World War II, he went on to become the organizer and de facto leader of the Milice française, or French Militia, the collaborationist Vichy government's paramilitary police force. Darnand also served as an officer in the Waffen-SS. He was tried and executed after the war for treason.

In World War II, many governments, organizations and individuals collaborated with the Axis powers, "out of conviction, desperation, or under coercion." Nationalists sometimes welcomed German or Italian troops they believed would liberate their countries from colonization. The Danish, Belgian and Vichy French governments attempted to appease and bargain with the invaders in hopes of mitigating harm to their citizens and economies.
