fund the movement, called at that time "La Jeune Nation", which held its first presentation on 22 October 1949 in Pajot's apartment. In 1952, they published a monthly magazine, Peuple de France et d'Outre-mer ("People of France and Overseas France"). The movement also tried to establish links with other nationalist right-wingers abroad, with Sidos traveling to London to visit fellow groups. They were soon joined by other nationalists like Albert Heuclin, Jean Marot, Jacques Wagner and Jean-Louis Tixier-Vignancour. On 23 March 1950, the group was officially declared to the Prefecture of Police, but it remained publicly unknown for several years. In 1954, two events changed the destiny of Jeune Nation: the end of the First Indochina War on July 20, and the beginning of the Algerian War of Independence on November 1. Street violence: 1954–1957 The movement experienced a sudden fame and membership rose after the return of military personnel from south-East Asia. On 11 November 1954, ten days after the beginning of the Algerian War, Pierre Sidos announced the official birth of the movement "Jeune Nation" under its final name. Tixier-Vignancour, opposed to violent actions, soon left the group to create his own organization, the Rassemblement National Français. Jeune Nation held its first congress on 11 November 1955, when they adopted the Celtic cross as their emblem. Dismissing mass parties, Sidos aimed at creating a small and faithful army, with a revolutionary general staff ready to seize power and rule as a military junta when their moment has come. 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, whose later opposition to Sidos marked a generational and ideological shift between the young "euro-nationalists" and the "nostalgic neo-Petainists of Pierre Sidos." If they were largely inspired by the ideologies of fascist Italy and Vichy France, Jeune Nation began at that time to break with the collaborationist circles that had been protecting them since Sidos' prison time. As Gaullists and former resisters were joining their ranks in the context of the Algerian war, Sidos banned any evocation of the period 1933–1945 among its militants, with only a few events like the commemorations of Robert Brasillach's death or the events of 6 February 1934 allowed to take place. The group was known for their violent street attacks, especially on communist sympathizers. On 9–10 October 1954,
