The catalan-Aragonese "Regnum Sardiniae et Corsicae" and the "Giudicato of Arborea" in the fourteenth century

To deal systematically with the study of the institutional systems in force in Sardinia in the fourteenth century, it is indispensable to start with a review of the literature and of the published documentation, in order to bridge some gaps in the historiography. Extensive research must then be undertaken at the main archives of the kingdoms of the Crown of Aragon,in both the Iberian and Italian settings. That said, this brief analysis still allows the initially critical areas to be highlighted, and some general and basic considerations to be formulated.
