Envisaging political power as dynamic allows the historian to deal with its structures with some sophistication. This paper approaches political power, not as a circumscribed block of bureaucratic elements, but as a complex phenomenon rooted in social reality. The authors explore the dialogue between local and central power, understanding ‘dialogue’ in its widest sense. Thus the relationships (both amicable and hostile) between local and central spheres of influence are studied. The authors propose a new analytical framework for the study of the configuration of political power in the northern zone of the Iberian peninsula, over a long period of time, which takes in both the post‐Roman world and the political structures of the early Middle Ages.
