In 1853 he was arrested for conspiring against Napoleon III, but was later freed due to a lack of evidence. He lived in poverty, writing journalism for bread (the stockmarket page of the Figaro even, until fired for his bias against capitalism). It was under these conditions that he wrote his first book L'Argent (1857). Les Amours de Paille (1859), a comedy written in collaboration with Poupart-Davyl, was a failure.(ref 1990 Alain Viala) At the insistence of his colleague Henri Rochefort he found an administrative job issuing birth certificates for the Vaugirard town hall.(1860) He became a steady friend of Hector Malot and began to live with his lover, Joséphine Lapointe. He decided to become a pion himself in Caen, but was quickly discharged. Back in Paris, his friend Hector Malot helped him reacquire his job at the town hall. In 1864-1865 he wrote literary criticism for Progrès de Lyon. In 1865 he collected much of his newspaper work in a book Les Refractaires that sold well. A second collection in 1866 La Rue had less success. In 1867 he started the newspaper La Rue, which was later suppressed by the government after a mere eight months of publication.
By this time he was a recognized leader of the republican opposition against the Second French Empire. In 1865 he had lost his job at Vaugirard for a speech he gave against the capitalist society of the Second Empire, eluding the censorship by advertising a talk on Balzac. In 1868 he was twice convicted for press crimes: one month in prison for criticizing the police, two months for criticising the Empire. At the elections of 1869 he was the candidate to the left opposing the moderate Jules Simon. He lost the election and went to work for La Marseillaise the newspaper of Henri Rochefort, meanwhile contributing to La Liberté of Émile de Girardin.
In the summer of 1869 members of several "Chambres syndicales" of Paris workers rented a space at nr 6, Place de la Corderie to hold the meetings of the "Chambre fédérale des Sociétés ouvrières", the "Conseil fédéral des sections parisiennes de l'Internationale", and as the events unfolded the "Comité central républicain des Vingt Arrondissements" (1870) and the "Comité central de la Garde nationale". (March 1871) It was to be the very organisational center of the Paris Commune. Its activities are prominently described in Jacques Vingtras:L'Insurgé. Jules Vallès had friends and connections among all the tendencies represented: Proudhon, blanquist,marxist and while he was himself independent of all of them he represented the active force of each. He was well known and well liked and when in 1870 the Government of National Defence spread the rumour that the candidates of the extreme left including Vallès had been on the payroll of the Imperial police at the 1869 elections, the Corderie gave him a vote of confidence.
The year leading up to the Paris Commune began with the assassination of Victor Noir (January 10). Jules Vallès and Henri Rochefort found themselves at the head of the mass manifestation at Victor Noir's funeral (January 12); Rochefort interceding with the blanquist Gustave Flourens who wanted to begin the anti-imperial insurrection there and then.
In July Napoleon III embroiled France in the Franco-Prussian War. Vallès was among the very few anti-war protesters, and was jailed as a consequence (August 6). On September 2 Napoleon III capitulated at Sedan and was captured. On September 4 the Third French Republic was proclaimed and the Government of National Defence installed.(Gambetta) Vallès was freed from prison and took part in the popular manifestations leading to the formation of the "Comité central républicain des Vingt arrondissements" of which he -like many other leaders of the Paris Commune- became a prominent member; heading even, for a while, a bataillon of the "Garde nationale". On September 18 the Prussians laid siege on a Paris unwilling to accept defeat and calling for all out war by the provinces. On October 5, Flourens marched the five bataillons "Garde nationale" of Belleville in disciplined military fashion to the Hôtel de Ville to show preparedness. On October 31, a first blanquist uprising erupted at Belleville with Vallès in command of his bataillon occupying the townhall of la Vilette. The uprising failed and Vallés had to go in hiding.
At the start of 1871 Jules Vallès at the initiative of the "Comité central républicain des Vingt arrondissements" edited the "Affiche Rouge" posted on January 7 : the first call for the proclamation of the Paris Commune. On Mars 11, Vallès was judged for his participation in the October plot. He escaped from the tribunal after hearing himself condemned to six months in prison, and his Le Cri du Peuple which he had started on February 22, banned from further appearance. On March 18, the Commune was officially proclaimed; March 21, Le Cri du Peuple reappeared to become one of the most successful newspapers of the Commune - together with Père Duchêne. On March 26 he was elected by the 15th district (Vaugirard: 4.403 votes of 6.467 voters) to the Conseil de la Commune; nominated to the commission of Public Education (March 29).
Although quick to the march when it came to demand individual liberties Jules Vallès was also a voice for opposite opinion: he claimed his reserve when the separation of Church and State was proclaimed (April 2), opposed the suppression of the "reactionary" newspapers (April 26), he voted against the institution of the Comité de Salut with its jacobin tendencies, and together with 22 other prominent members - among them his old friend Arnould, the painter Gustave Courbet, Vermorel, Varlin...he signed the manifest of the minority which he published in his newspaper. (May 15)
On May 21 the Versailles troops entered Paris through the porte Saint-Cloud while Vallès, among minority members reintegrated in the Commune, presided over its last session - in judgement over Cluseret and his failure to hold the fort of Issy (and with Vallès in sympathy with the defendant). During the Semaine Sanglante (May 21 – May 28) he took part in the fighting, making a last stand in the rue de Paris (now rue de Belleville) on May 28 with his steadfast friend Gabriel Ranvier. Together they managed to escape the fusillades and went into exile. In 1872 both were given death sentences in absentia.
Its collaborators were: Casimir Bouis, Jean-Baptiste Clément, Pierre Denis, Charles Rochat with occasional articles by Henry Bauer (1851-1915), Courbet and André Leo.
Because of the communal tasks taken up by most other editors the work of chief editor in practice fell to Pierre Denis who set the tone with accent on the Proudhonian ideology, whose tendencies he represented in the First International of which he was a member: recognition of individual liberties, suppression of the permanent army and police, "Laïcité" and free education, entire benefit of work produced, autonomy of the commune -or Voluntary association, autonomy, federation, union.
Jaques Vingtras was not written in composed sessions but gestated during the bitter exile following the Paris Commune.
Jules Vallès went to live in London. In 1875 Vallés, in the absence of Joséphine Lapointe, had a little daughter with a woman he rapidly separated when the child died, 10 months old. The event marked his complete destitution in 1876. His friend Hector Malot then negotiated the appearance of Jaques Vingtras - L'Enfant as a serial (feuilleton) in the newspaper Le Siècle (June-August 1878). The extreme realism combined with corrosive irony led to public reaction and abortion of the project. In January-May 1879 Le Bachelier appeared in La Révolution française under the title Les Mémoires d'un révolté. The first book Jaques Vingtras - L'Enfant, Le Bachelier was published by Charpentier and signed 'Jean La Rue' (Vallès had tried to start the paper La Rue in Brussels that same year - a failure).
In 1879-1880 he came to know Séverine, whose friendship secured the final draft of L'Insurgé and who caused Chapentier to publish the book (1886) after Vallès death.
Among the French authors most influenced by the racy, concise and ironic style of Jules Vallès the author of the child's portrait Poil de Carotte, Jules Renard must not be forgotten. Séverine at least recognised the prose of her friend in his writings (see: Jules Renard Journal 1897-1910)
In 1883 he was entirely successful in restarting Le Cri du Peuple as a voice for libertarian and socialist ideas. At the same time he became increasingly ill with diabetes. During a health crisis in November 1884 he was taken to the house of doctor Guebhard and his wife Séverine. He assigned Hector Malot to be the executor of his will and died on 14 February 1885.
His funeral also became a popular manifestation with some 60,000 following the coffin to Père Lachaise.
