In 1904, the history professor Amédée Thalamas enjoyed a small reputation for having relativized the political role of Joan of Arc during the Hundred Years War and questioned her virtue as well as the supernatural character of the virgin of Orleans.

Trained by Maxime Real del Sarte, the Camelots du Roi decide to interrupt the lesson given by the professor every Wednesday, even if it meant resorting to violence.

The young people left the room, spread out on the boulevard Saint-Michel, broke through the police roadblocks, crossed the Seine, and arrived at the statue of Joan of Arc, where they laid a wreath of flowers.

The first trial against a Camelot du Roi took place on 24 December: Serge Real del Sarte, a student at the Ecole des Beaux-Arts, was accused of "violence against an agent".

[17][18][19] The Camelots du Roi imagine themselves "in the most working-class neighborhoods, in the reddest suburbs of the outskirts with a certain guts, sometimes expelled by a stubborn police commissioner, as in Javel, or by a mayor [...] like in Issy-les-Moulineaux ».

[21] [check quotation syntax] From February 17 to April 20 in Vigneux, the Camelots du Roi build and furnish twenty-five barracks for workers, with the help of the Marquise de Mac Mahon and the Association of Young Royalist Girls.

[22] On the night of November 19 to 20, 1910, Camelots plastered the walls of Brest with a poster entitled Les Gloires de la République, which depicted a fat Jewish woman — wearing a Phrygian cap and Masonic garb, and attacked with virulence the Chairman of the Board Aristide Briand and Joseph Reinach nicknamed "Reinach Boule-de-Juif" (stings about his overweight, in reference to a short story by Maupassant titled Boule de Suif).

The Camelots du Roi and the leaguers take part in numerous contradictory conferences as well as demonstrations in several cities: Bordeaux, Nice, Toul, Epinal, Toulouse, Limoges, Dijon, Orléans, Lille, Lyon, Rennes.

The historian Rosemonde Sanson recalls that "the press campaigns carried out by groups of moderate republicans, the creation a little later of the Federation of the Lefts on the eve of the legislative elections of 1914 had, without a doubt, a greater repercussion".

[32] In 1916, some sections nevertheless managed to maintain a rhythm and ensure meetings, such as in Bordeaux, Toulouse, Marseille, Nogent le Perreux, Rouen, Angers, Montpellier, Chambéry, Nantes, Riom and Saint Germain en Laye.

[34] On January 22, 1923, the Secretary General of the Camelots du Roi, Marius Plateau, was assassinated by Germaine Berton, an anarchist militant, to avenge Jean Jaurès and Miguel Almereyda, and also to protest against the occupation of the Ruhr.

On the evening of 31 May 1923, the Catholic Marc Sangnier, the radical Maurice Violette, and the socialist Marius Moutet spoke at a meeting in the hall of learned societies against "French fascism".

[42][41] As a repeat offence, the Camelots du Roi sabotaged a meeting of the University Beam[clarification needed] at the Salle d'Horticulture in Paris on 15 December 1925 by routing Georges Valois[43].

On November 27, 1931, the Camelots disturbed the International Disarmament Congress, organized by the School of Peace of Louise Weiss, at the Trocadéro in Paris and brought together several thousand people from around forty different countries.

After three days of siege which gave rise to major fights with the police, the prefect Jean Chiappe obtained the surrender of the two main madmen, who were immediately imprisoned in the prison de la Santé.

On June 25, 1927, the telephonist Charlotte Montard escaped Léon Daudet, Joseph Delest and the communist Pierre Semard thanks to a hoax telephone call to the Director of the prison.

For this plan, Charlotte Montard delegates to a dozen Camelots du Roi, including André Real del Sarte and Pierre Lecœur, the responsibility of saturating the prison telephone lines.

Pierre Lecœur, secretary general of the Camelots du Roi, was accused of being a police informant by Bernard de Vesins, Henri Martin and Paul Guérin.

On December 25, 1933, on the orders of the sub-prefect Antelme, the director of the Municipal Credit of Bayonne Gustave Tissier was arrested for fraud and putting into circulation false bearer bonds for an amount of 25 million francs.

It was quickly discovered that Tissier ws only the executor of the founder of the Communal Credit, Serge Alexandre Stavisky, who organized this fraud under the complicit supervision of the Deputy Mayor of Bayonne, Joseph Garat, who was sentenced to two years in prison.

At the same time, a large demonstration was organized in Paris, Place de la Concorde, at the call of several right-wing leagues including the Camelots du Roi on the theme: "Down with thieves!"

[52] Other incidents occurred at the Sorbonne, such as the campaign against the law professor Gérard Lyon-Caen, of the Jewish faith, whom the Camelots du Roi succeeded in putting into early retirement;[23] or the intervention of Maurice Pujo bursting into a university classroom and dismissing the lecturer to give a lesson on French Action.

[53] Action Française, which exerted a great attraction in the medical community thanks to the rallying of eminent members of the profession, interfered in this debate by placing the blame on foreign doctors and students.

On December 9, 1935, 97 Camelots du Roi from the 17th team of the 16th arrondissement of Paris sent a Memorandum on immobility (French: Mémoire sur l'immobilisme) to Maurice Pujo, Georges Calzant and Maxime Real del Sarte, accusing them of letting the movement collapse.

Some engaged in resistance like Daniel Cordier, Jean Ebstein-Langevin or Paul Collette while others preferred to take the path of collaboration like Jacques de Mahieu, Henri Martin, Robert Brasillach or Joseph Darnand, former Camelots du Roi, some of whom had already broken with Action Française before the war.

After the incarceration of the 15-year-old militant Roger de Vasselot, Maurice Pujo authorized membership of the King's Camelots only from the age of 18 in 1909 and demanded an investigation into the profession and the resources rookies.

Some intellectuals emphasize this aspect, such as the historian Daniel Halévy, despite being a Dreyfusard and close to Charles Péguy, who describes the 24 May gathering of young people who were members of the Camelots du Roi and the Action française like a "spectacle so rare in our Parisian streets, this virile elegance, this beauty, this nobility…".

Some prominent figures report extremely virulent remarks such as those of Bernanos who wrote to Professor Alain, in response to one of his articles in a Rouen republican newspaper : "It's not your idea that I despise, it's you".

[8][74] Acting as both the Action Française security service, shock troops and activists of the movement, they fairly quickly caught the concerned attention of those in power, and above all of Aristide Briand who saw in them and in their violence poses serious dangers to the order and maintenance of the Republic.

This traditional royalism seemed to have won when, on 20 March 1910, Le Gaulois published an interview with the Duke of Orléans, who denounced the violence of the King's Camelots, and who brandished the threat of a formal disavowal if their militants "continued not to distinguish between friends and enemies, and if a persistent error of maneuver pushed them to direct their fire on the bulk of the royalist troops".
