In the autumn of 1744, amidst the turmoil of the War of the Austrian Succession, an anonymous, rather lengthy pamphlet entitled Représentation aux Etats de l’Empire appeared in print. It addressed the members of the Reichstag (the Imperial Diet) and urged them to take sides with Charles VII, Holy Roman Emperor, against Maria Theresa, Archduchess of Austria and Queen of Hungary and Bohemia. The Représentation circulated widely across Europe, and copies can still be found in Germany, Sweden, Slovakia, and the Netherlands, as well as in France. However, the sudden death of Charles VII on 20 January 1745 rendered the project expounded in the Représentation utterly impracticable, thus dooming the pamphlet to be quickly forgotten.
The Représentation briefly resurfaced in 1887, when Jacques-Victor-Albert, duc de Broglie, republished the pamphlet in the first issue of the Revue d’histoire diplomatique. De Broglie identified the author of the pamphlet as none other than Voltaire, and made the further claim that the latter had produced the text at the request of the marquis d’Argenson, then Secretary of State for Foreign Affairs. Nevertheless, probably because de Broglie provided very little evidence to support his argument for Voltaire's authorship, the Représentation again failed to garner long-lasting attention and, to the best of my knowledge, no further mentions of it were made in Voltairean scholarship.
In July 2015, however, I made a discovery that was to shed new light on this question. As I was working in the Archivio di Stato di Firenze, I found 170 letters from Nicolas-Charles-Joseph Trublet to Luigi Lorenzi, French Resident Minister to the Grand Duchy of Tuscany. Many of these letters provide insights into Voltaire’s activities in the 1740s. A letter dated 1 March 1743, in particular, the main subject of which is Voltaire’s comédie-ballet La Princesse de Navarre, proceeds explicitly to mention Voltaire as the author of the Représentation aux Etats de l’Empire. After unearthing this document, I decided to investigate further. Off I went to Paris, and after a few days of research at the Archives du Ministère des Affaires Etrangères, the papers of Malbran de Lanoue (French ambassador to the Imperial Diet from 1738 to 1749) yielded a manuscript of the Représentation aux Etats de l’Empire. This manuscript is not in Voltaire’s hand, nor in that of any of his known secretaries. However, it bears several corrections which are in his hand. Furthermore, a marginal note on the front page reads: ‘cet écrit est du poète Voltaire’. Study of this manuscript soon revealed significant similarities with other Voltairean texts, notably the Histoire de la Guerre de 1741, the Précis du siècle de Louis XV and the Mémoires pour servir à la vie de Monsieur de Voltaire. It also showed, however, remarkable differences from the text of the 1744 print edition that de Broglie had republished in the Revue d’histoire diplomatique in 1887. Another manuscript which I found amongst de Lanoue’s papers – the ‘Remarques de M. de Bussy sur l'écrit intitulé Représentations [sic] aux Etats de l'Empire de M. de Voltaire de novembre 1744’ – revealed that the manuscript of the Représentation had in fact been sent to diplomat François de Bussy for revision, before it was sent to press in 1744. A manuscript with corrections in Voltaire’s hand, a marginal note unequivocally asserting Voltaire’s authorship, several textual similarities with other Voltairean works, an endorsement from Trublet… There seems to be sufficient evidence to include the Représentation aux Etats de l’Empire in the Œuvres complètes de Voltaire!  – Ruggero Sciuto  A critical edition of the Représentation aux Etats de l’Empire will be published in the forthcoming volume 29 of the Voltaire Foundation’s Œuvres completes de Voltaire, alongside Janet Godden and James Hanrahan’s edition of the Précis du siècle de Louis XV. In a brief introduction, I shall provide further evidence of Voltaire’s authorship and details on the pamphlet’s complex publication history. I shall also discuss the relationship between the Représentation and other diplomatic despatches that Voltaire penned on behalf of the marquis d’Argenson in the mid-1740s – e.g. the Lettre du Roi à la Czarine pour le projet de paix of May 1745, the Manifeste du Roi de France en faveur du prince Charles Edouard of December 1745 and, most importantly, the Représentations aux Etats-Généraux de Hollande (all three texts are already available in the Œuvres complètes). Finally, I shall consider François de Bussy’s interventionist approach in preparing Voltaire's manuscript for publication, which further complicates the crucial question of authorship.
