[1] A veteran of World War I, Darquier had been active in Fascist and antisemitic politics in France in the 1930s, being a member, at various times, of Action Française, Croix-de-Feu and Jeunesses Patriotes.

During this period Darquier began collaborating with the noted antisemitic publisher Ulrich Fleischhauer's Welt-Dienst (World-Service or Service Mondial) organization based in Erfurt, Germany.

[4] At Nazi Germany's behest, he was appointed to head Vichy's Commissariat-General for Jewish Affairs in May 1942, succeeding Xavier Vallat, whom the SS in France found too moderate.

[5] Darquier's ascent to this post immediately preceded the first mass deportations of Jews from France to concentration camps.

ON 10 December 1947 He was sentenced to death in absentia national degradation for life and the confiscation of his property by the French High Court of Justice for collaboration.
