Dennis W nails it. The Crusades were not an important part of the Islamic countries’ history of themselves until they started coming in contact with European historians in the early 19th C. They had, frankly, ignored it as less important than their own wars with each other and their more directly territorial wars of slaughtering Romanians and Bulgarians. Kaska’s complaint about images of the Knights Templar only come up because he learned about them from Europe.
