This article attempts to determine the composition and functions of the Royal Court in Late Medieval France, and also to estimate the principal lines of its transformation under the influence of the process of the separation from the Curia Regis the state administration bodies (Chambre des Comptes, Parlement, Conseil du Roi, Chambre du Trésor, Chambre des Aides). The author investigates the process of institutionalisation of the Household’s services (chancelier et Chancellerie, Chambre des Requêtes de l’Hôtel, Chambres aux Deniers), the extension of competence, the interconnection with the Royal Palace bodies, the emergence of the court society and new representative image of the Royal Court.
