Fronteras de aire. Portugal, León y castilla en el siglo XIII

Abstract

Studied documents illustrate a close link between the kingdom of Portugal and the kingdoms of Castile and Leon in the 13th century. They demonstrate a diplomatic tradition that tended to guarantee a balance of power between them in spite of events that would eventually divide them, such as the union of Castile and Leon. This century was a diffi cult one for the three kingdoms due to wars, child monarchs, problems with the nobility, territorial and border consolidation, etc. Nevertheless, aspects related to history, geography, society, family, the economy and the church, well refl ected in these documents were without doubt, a driving force behind the unique relationship between the kingdoms. A preliminary glance at these documents illustrates the issues that both united and separated Portugal with Leon and Castile at the height of the medieval period.
