[en] In the frame of the process of political centralization undertook by the Trast?maras, in special during the fifteenth century, scholars have traditionally regarded the institution of the ?corregimiento? (the ?corregidores? ?keepers of the town? were royal agents appointed to oversee the government and, in general, administration of royal cities and towns) as one of the most perfect instruments highlighting the stages and intensity with which that aim was achieved. Historians have considered the imposition of the ?corregimientos? over the towns as a defeat of the urban world, as a trait of weakness on the part of those towns especially predisposed to subject themselves to the political interference represented by these royal officials. Nevertheless, we know that towns were able to face the imposition of these agents with some degree of success. In some circumstances, they not only managed to avoid the appointment or even the effective inauguration into office of these officials but, in many cases, the ?corregidor? inauguration constituted the last phase in a process of negotiation not necessarily conducted with the monarch but singularly with the royal agent. These negotiations helped to lubricate the relationship thus generated between both parties, redefining it in terms of political cooperation. The aim of this paper is to demonstrate the way in which these royal agents were perceived in the frame of those processes of relationship ?sometimes endowed with a conflictive nature, sometimes showing negotiating traits?, and the ability showed by cities and towns to develop an autonomous political action in the frame of the more global process of political centralization. The terminus ad quem of this paper is the Toledo of 1480, it implies the beginning of a different phase in the process of institutional consolidation of the ?corregimiento?.

[es] En el marco del proceso de centralizaci?n pol?tica emprendida por la dinast?a Trast?mara, especialmente a lo largo del siglo XV, la instituci?n del corregimiento ha sido tradicionalmente considerada como uno de los m?s perfectos instrumentos que ilustran las etapas e intensidad con la que se avanz? en el desarrollo de ese objetivo. La imposici?n de corregimientos a las ciudades ha sido considerada por la historiograf?a como una suerte de derrota del mundo urbano, de especial debilidad de aquellos concejos m?s proclives a someterse a la injerencia de estos oficiales regios. Sin embargo, nos consta que las ciudades fueron capaces de enfrentarse a la imposici?n de estos agentes con cierto grado de ?xito. No solo lograron, en determinadas circunstancias, evitar el nombramiento o el recibimiento del oficial sino que, en muchos casos, la recepci?n del corregidor constituy? la fase final de un proceso de negociaci?n llevado adelante no necesariamente con el monarca sino singularmente con el agente regio. Una negociaci?n que lubric? la relaci?n as? generada entre ambas partes, redise??ndola en t?rminos de colaboraci?n pol?tica. El objeto de este estudio es precisamente poner de manifiesto el modo en el que se percibe a estos agentes regios en el contexto de esos procesos de relaci?n, conflictiva en unas ocasiones, negociada en otras, y la capacidad de acci?n pol?tica aut?noma que cabe atribuir a las ciudades en ese marco de pol?tica centralizadora. El terminus ad quem del estudio viene constituido por la inauguraci?n de la monarqu?a isabelina, que supone, ya desde las Cortes de Toledo de 1480, el inicio de una fase distinta en el proceso de consolidaci?n de la instituci?n del corregimiento.
