POWER, MONARCHY AND NOBILITY ON THE FRONTIERS OF THE CROWN OF ARAGON. THE DISPUTE BETWEEN JAMES I AND BLASCO DE ALAGON FOR THE TOWN OF MORELLA (1231-1239)

This article analyses the conflict that arose between King James I and the noble Blasco de Alagon for the possession of the town of Morella, on the frontier of the Crown of Aragon. Our intention is to analyse this episode to know the discourses, practices and exercise of the power of the monarchy and the nobility in the middle decades of the thirteenth century. To do so, attention is focussed on the chronicle of James I and the documents that were produced during the dispute. However, we also have to consider the silences in the respective sources, as these are highly significant for understanding the actions of the two protagonists and their concept of power.
