Loustallot left Bourdeaux and arrived in Paris in 1787. The year 1788 marked the largest crop failure in France in the 18th century, exacerbating pre-existing tensions. During this time, Loustallot worked in the authorship and translation of pamphlets. On June 17, 1789, the Third Estate voted in the Hotel des Menus Plaisirs 490-90 to form the National Constituent Assembly. This act is taken to mark the political birth of the French Revolution. Shortly thereafter, J. L. Prudhomme founded and financed the "Revolutions of Paris", where Loustallot joined as the founding editor and a major author. Loustallot's "Revolutions of Paris" printed its inaugural issue on July 17, 1789, three days after the sans-culotte rebels succeeded in storming the Bastille. In its first fourteen months of publication, he personally wrote the first sixty issues of the newspaper. In 1790, with the recent lax in censorship laws and the tide of revolutionary sensationalism, Paris had 133 journals being published. The "Revolutions of Paris" was considered to be among the most distinguished and impartial of the lot. Loustallot became seriously ill and frail in 1790. However, he still managed to publish his last issue of the "Revolutions of Paris" on September 4, 1790, two weeks before his death. His final work was a commentary on the Nancy mutiny. He died on September 19, 1790 at the age of 28. After learning of his death, the Jacobins sent Maximilien Robespierre and Louis Sébastien Mercier as representatives to his funeral. The Jacobin and Cordelier clubs mourned his death for three days. Loustallot was the main contributor of the "Revolutions of Paris" up until his death. Prudhomme continued publishing the paper, with later writers Chaumette, Sylvain Maréchal, Fabre d'Eglantine, and Saintonax continuing on the journalistic standards of Loustallot. He is remembered as being a moderating voice against bloodshed, while passionately prescribing to republicanism in the early stages of Revolutionary France.
