Let's say that, by a combination of avoiding at least some of the unlucky breaks that did major damage to them (e.g. Stephen of Blois getting blackpilled about the crusade and abandoning it literally the day before the crusaders took Antioch and inadvertently convincing Alexios that the whole thing was a lost cause, causing the crusaders to waste six months around Antioch waiting for the emperor and permanently souring relations between the crusaders and the Byzantines) and playing their weak hands better than they already did, at least some crusader states survive and become stable fixtures in the Mediterranean. As an example of what a surviving crusader Levant could feasibly look like, not saying this setup is inherently part of the hypothetical, say the end result of the Crusades is a Kingdom of Jerusalem that also includes Mount Lebanon and a secure northeastern flank-possibly even secured by taking Damascus outright-where the majority is Christian but Sunni Islam remains the largest single religious sect and a crusader Kingdom of Egypt where the majority follows a Coptic Church that is likely to have entered communion with Rome.
Assuming history back in Europe continues more or less on the trajectory it did IOTL in spite of this, how will Europe's upper classes and chattering classes regard these offshoots of a bygone age once the Industrial Revolution gets underway? Would they, or at a minimum the crusader descendants among their upper classes, be begrudgingly regarded as 'honorary Europeans', so to speak? Would they be dismissed as Orientalized backwaters that Occidental commercial interests should have no qualms slapping around? Would they be regarded, at least by Protestants and/or Whigs and/or various anti-clericalists, as faintly risible anachronisms, reminders of an embarassingly backwards Europe best left buried? What would their influence on the arts be? How would they be integrated into the European-Mediterranean economy? And so on.
