Misconceptions about the Crusades are all too common. The Crusades are generally portrayed as a series of holy wars against Islam led by power-mad popes and fought by religious fanatics. They are supposed to have been the epitome of self-righteousness and intolerance, a black stain on the history of the Catholic Church in particular and Western civilization in general. A breed of proto-imperialists, the Crusaders introduced Western aggression to the peaceful Middle East and then deformed the enlightened Muslim culture, leaving it in ruins. For variations on this theme, one need not look far. See, for example, Steven Runciman’s famous three-volume epic, History of the Crusades, or the BBC/A&E documentary, The Crusades, hosted by Terry Jones. Both are terrible history yet wonderfully entertaining.
