This article aims to investigate what may have been Thomas Paine's influence on the Girondin constitutional project presented by Marie-Jean-Antoine-Nicolas de Caritat Condorcet to the French National Convention, of which he was a member, on 14 and 15 February 1793. Indeed, the English radical was part of the nine-member committee, by the majority Girondin faction, in charge of drafting a new constitution for France. That project, which was accompanied by a Declaration of Rights, never came to fruition, but it has always been recognized as an important document for the interpretation of the evolutionary dynamics that characterized the French revolutionary period. Many of the provisions in the constitution recall Painite political thought, and studying this element can also be useful for understanding the links between the American and French Revolutions, given the fact that Paine actively participated in the experience of institutional upheaval initiated by the American colonists in 1775. The English thinker elaborated a political theory in his writings inspired by the most important democratic principles and based on respect and protection of fundamental human rights, all elements that, in their different mode of expression and declinations, can be found again in the Girondin constitutional charter of 1793.
