Labeling themselves the "successors of those of 1934" and targeting young people in their recruitment, Jeune Nation was joined in 1956 by Dominique Venner, then 21, who would later oppose Sidos and mark a shift between his euro-nationalist doctrine and the "nostalgic neo-Petainists of Pierre Sidos." Although they were largely inspired by the ideologies of fascist Italy and Vichy France, Jeune Nation began to break with the collaborationist circles that had been protecting them since Sidos' prison time. As Gaullists and former resisters were joining their ranks during the Algerian war, Sidos furthermore banned any evocation of the period 1933–1945 among its militants, with only a few events like the commemorations of Robert Brasillach or 6 February 1934 allowed to take place.
