In the kingdom of Aragon the opportunities of the crown were not so great. The Cortes had more extensive powers, the nobles were more regular in their attendance, and there were no military orders whose masterships might be annexed. Above all, the peculiar privilege of the ‘Justiza’ formed a serious obstacle to royal encroachment. This notable officer, elected by the Cortes, claimed the right of hearing all appeals, of inquiring into the legality of any arrest, of advising the King on constitutional questions, and of sharing the executive with him. Even here, however, Ferdinand excluded his nobles as far as possible from political power, ruled with the aid of commoners whose fidelity could be more safely relied upon, and introduced the Castilian Hermandad. The Catholic sovereigns also turned their earnest attention to church reform. The relations between Church and State had always been close in Spain. The long Crusades against the Moors had given the crown a peculiar position of which it had taken advantage. It was the aim of Ferdinand and Isabella to subordinate still further the Church to the royal will, and use it as an engine at once for extirpating heresy, and increasing the royal authority. Having, in 1482, gained from Pope Sixtus IV. the right of exclusive nomination to the higher dignities of the Church, the sovereigns proceeded to make excellent use of their prerogative. The sees of Spain were filled with men of energy and devotion, and the work of reform begun. Cardinal Mendoza, Talavera (the first confessor of the queen), and, above all, the famous Franciscan friar, Francisco Ximenes de Cisneros, were the chief agents of the royal policy. | Administration of Ximenes.
