The legend of the Princess of Navarre A founding myth of the judges of Arborea's dynastic identity in their political, military and ideological conflict against the kings of Aragon in the fourteenth century

Around the mid-fourteenth century the relationship between the King of Aragon, as sovereign of the Kingdom of Sardinia and Corsica, and the Judge of Arborea began to change after nearly three decades of peaceful coexistence within the limited geographical area of Sardinia. At that time, the Judge Marianus IV was facing a juncture: to remain faithful vassal of the King of Aragon and, thus, to reconcile with an inevitable reduction of his own role in the island; or torespond to a policy of increasing political and institutional centralisation by King Peter IV, well manifested in the simultaneous annexation of the Kingdom of Mallorca to his Crown.
