On the eve of the French Revolution, Marat placed his career as a scientist and doctor behind him and took up his pen on behalf of the Third Estate. In January 1789, he published his "Offrande à la Patrie" ("Offering to the Nation") which touched on some of the same points as the Abbé Sieyès' famous ""Qu'est-ce que le Tiers État?"" ("What is the Third Estate?"). This was followed by a "Supplément de l'Offrande" in March, followed in July by "La Constitution, ou Projet de déclaration des droits de l'homme et du citoyen", intended to influence the drafting of France's new constitution, then being debated in the National Assembly.
