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. She then sent her husband
Brancaleone to deal directly with the sovereign. At the same time she sent a letter to the queen, asking her to intercede with her spouse in favor of her son so that she could end the disorder that reigned on the island. Eleanor intended to reunite in the hands of her son those two thirds of Sardinia that
Hugh, before his death, had occupied. 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.
Brancaleone was detained under the pretext of having him return to
Sardinia as soon as a fleet was set up, but he had actually become a real hostage (and instrument of pressure against the rebellious judgess). 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. In practice, the elective praxis was the opposite of the
royal fiefdom and was at variance with the Aragonese political line. 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). The reason that the viscount Aymeric brought forward consisted in the decisive fact that his wife, Beatrix, was the second child of
Marianus IV and Timbora di Roccaberti, after
Hugh III and therefore before Eleanor. Her succession therefore belonged to the Narbonne-de Serra Bas branch, as mentioned and documented above: the fact that she gave her the name of Timbora's mother, Beatrix, is also further proof. 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. == Political life and death ==
