Agreda is the typical case of a Castilian town by the border. The kingdoms of Castile, Navarre and Aragon wished it. Very frequently, the peace from the Iberian Peninsula was at stake within its limits. It was the meeting point of three cultures: Arabic, Jewish and Christian. Reconquered by Alphonse I The Battler in 1118. It was repopulated by people from the northeast of Soria: Yanguas, San Pedro Manrique and Magaņa, during Alphonse VII. All the Castilian monarchs, during the Middle Ages, gave this town a large quantity of privileges, so that it remained loyal to them to the detriment of the other bordering kingdoms. This period gave rise to royal weddings (in 1221 James I The Conqueror married Lady Eleanor from Castile), pacts, meetings and quartering.
