It now seems certain that in 1382 Eleanor gave a loan of 4,000 gold florins to Nicolò Guarco, doge of the Republic of Genoa, and that the latter for his part undertook to repay the sum within ten years; otherwise, he would have paid double.

[5] A similar loan to a powerful family of Genoa, and this clause of the contract, indicate a dynastic design by Eleonor who, by granting this credit, together kept the prestige of her lineage high and recognized the importance of the interests of the Ligurians.

Recent studies, based on a letter from Aimery VI of Narbonne, husband of Beatrix, to King Peter IV of Aragon, in which he claimed the Arborean throne for his son William II, immediately after the death of Hugh III), ascertain that Eleanor was the third child of Marianus and Timbora.

The external reasons for the murder were those of the Aragonese and the enemies of Arborea; the internal ones could be identified in the discontent of the classes of owners and merchants, in reaction to the authoritarian attitude of Hugh III and for the vexatious contributions (necessary to keep the German, Provençal and Burgundian mercenaries).

In this climate of crisis and discontent, with Aragon already openly willing to conquer the entire island, in 1383 Eleanor wrote a report to the king on the conditions of Sardinia and asked him to recognize her son Fredrick as the legitimate successor of Hugh.

This design made the aragonese sovereign suspicious, who did not consider it convenient to have such a powerful family in his kingdom, especially since there was no direct male heir to Hugh, those possessions, "iuxta morem italicum", should have been forfeited by the tax authorities.

Eleanor did not lose heart and confirmed her war policy: she took action and as soon as she returned to Oristano, she punished the conspirators and proclaimed herself Judgess of Arborea according to the provisions dictated by her grandfather Hugh II, for which women could succeed to the throne in the absence of male heirs.

The Arboreas instead recalled their ancient autonomy of early medieval origin and the right to exercise full sovereignty in their territories, a situation often contested or not recognized by the crown of Aragon.

Eleonora was in fact very worried because even her brother-in-law Aimeriy VI de Narbonne (1341–1388), widower of her sister Beatrix, had worked with King Peter IV of Aragon to convince him to recognize his son William I as judge of Arborea (1388 –1397).

Finally, the Aragonese monarch decided that his nephew Fredrick, eldest son of Eleanor (who would hold the regency) and Brancaleone Doria (whom he imprisoned), would take over from the murdered sovereign of Arborea.

Rather than from pre-existing elements, they seem to originate from the "ability of the Sardinians, free from foreign domination to self-manage" through complex forms such as those of the curatorial system, the assembly administration of the coronas de logu.
