In 1076, some twenty years before the First Crusade waslaunched, Pope Gregory VII wrote to al-Nāşir, Sultanof Bougie in what is now Algeria:
For there is nothing which Almighty God, who wishesthat all men should be saved and that no man shouldperish, more approves in our conduct, than that aman should first love God and then his fellow men …Most certainly you and we ought to love each otherin this way more than other races of men, because webelieve and confess one God, albeit in differentways, whom each day we praise and reverence as thecreator of all ages and the governor of this world.For, as the Apostle says: “He is our peace, who hathmade both one”.
This enlightened view of Islam was not widely shared inLatin Christendom at that time, nor was it rooted inany very profound knowledge of the Muslim religion.B. Z. Kedar is, I think, correct in his view that agood deal of information about Islam was availablein the West before the crusades, both in written andoral sources, but because there was a general lackof interest in the subject, no attempt had been madeto coordinate this knowledge.
