a commando led by Sidos carjacked a van transporting issues of the communist newspaper L’Humanité Dimanche, then destroyed them and assaulted the driver who died a few months later as a result of his injuries. Hoping to calm down the situation, Sidos sent a letter to the newspaper Le Monde a few days later to "formally disapprove of the individual violence committed in recent times". In March 1958, Jean-Marie Le Pen testified at the trial of four Jeune Nation militants accused of being involved in the murder. During demonstrations organized held on 8 November 1956 to denounce the Soviet military intervention in the Hungarian Uprising, Jeune Nation stormed and partly set to fire the headquarters of the Communist Party in Paris. In the midst of protests at place de l'Étoile in April 1954, they mauled Prime Minister Joseph Laniel and Minister of Defense René Pleven, and on 25 November 1957 Jeune Nation organized a violent protest in front of the American embassy to denounce arms exports towards Algeria. Dissolution and recreation attempts: 1958–1960 Jeune Nation was dissolved on 15 May 1958 by an official decree of Jules Moch, then Minister of the Interior, two days after the putsch of Algiers and the beginning of the May 1958 crisis. The group was involved in the troubles of May 13 in Algeria, and had been suspected of a bomb attack that occurred on February 6 in a lavatory at the National Assembly.

The new organization was designed by Venner as a coordination structure for all French far-right movements via a Comité d’Entente (Entente Committee).
