The religious factor in the political and social activities of the high nobility lineages in the region of soria at the end of the Middle ages

Abstract

The author analyses some aspects of the religiosity and of the policy adopted by the members of the High Nobility in their relationship with the ecclesiastical institutions in the Crown of Castile at the end of the Middle Ages. In order to be able to analyse this subject in greater depth, he chooses the Castilian region that had its capital in the town of Soria. He pays attention to the three noble lineages that exercised greater political influence in this region: the Arellano, counts of Aguilar, the Mendoza, counts of Monteagudo, and the La Cerda, counts and later dukes of Medinaceli.
