defenderías
Defenderías were a type of public office in medieval and early modern Spain, primarily responsible for the defense and administration of frontier territories. The term "defendería" refers to both the office itself and the region it governed. These officials were often appointed by the king and held significant military and judicial authority. Their main duties included organizing local militias, protecting the populace from raids and invasions, settling disputes, and collecting taxes or tributes from the territories under their charge.
The specific powers and responsibilities of a defender varied depending on the era and the particular region.
