Using the same documents, historians from Castile and Catalan gave totally different approaches to caspe`s agreement, by which the Castlllan Fernando de Antequera was elected KIng of Aragon. Both groups of historians belong to the twentieth century and transpose to the year 1412 the vision of the advantages and disadvantages of Spanish unity. According to the opinion, there is a negative of this agreement of those who know that Catatonía should regain the independence of the Middle Ages. Others give a highiy positivo versión, because they are convinced that Caspe favored the birth of Spain with the joint of the crowns of Castiie and Aragon. Faced with the nature of the problem, Marti I, a conscientious observer of constitutional traditions, made great efforts to involve the kingdom in the discussion and asked the Corts to send him delegates with whom he could discuss the issue. It also sought the advice of legal experts on fundamental issues such as the limits of its decision-making powers in this area and the extent to which family ties were considered legally valid. But the slowness of the delegates` deliberations did not lead to solutions, so that to the captivating and insinuated question of the deathbed of Ferrer de Gualbes, member of the Council and head of a delegation from the city of Barcelona, if the king accepted that his thrones be inherited from the one who had the best right to the Via Dejusticia, Martl`s affirmative answer was a weak “hoc” answer, which was repeated in Catalan. The day after the death of the king, arrangements were made to resolve the question of succession in the most qualified and largest forum available: a general procession of the three most important states of the Crown of Aragon: Aragon itself, with Valencia and Catalonia. But the violent conflicts between the noble factions – Urrea and Luna in Aragon, Centelles and Vilaragut in Valencia – put the plans in the void. That is why another solution was sought, namely agreement between selected committees and delegations designated by the Assemblies and which had become the only recognized form of authority in the country during the inter-period.
