Echoes of the Eastern Crusade in the Iberian Peninsula through pontifical documentation (12th-13th)

For a long time, from the end of the eleventh century until the first decades of the thirteenth, the Eastern Crusade was a key issue of concern to the pontificate. The popes reported on it in numerous encyclicals and informative letters to the whole of Christendom. Of course, these documents were also sent to the Iberian Peninsula, another scenario of confrontation against Islam. For this reason, the information sent to the Peninsula was measured and was conditioned by the circumstances governing the relations between the pontificate and the Iberian kingdoms in such a sensitive matter as the crusade.
