A word of warning: premodern men—kings or chroniclers, Muslims or Christians—were by today’s standards vociferously candid and spared no invective for what they deemed was the source of conflict—namely, the belief system of the other. Although their aspersions are usually seen as unnecessarily provocative hype and thus left out of polite histories, I have kept a fair amount in this book in the belief that they go a long way in explaining how each saw the other, and hence why they fought and died.
