This is a continuation of previous posts. When the Crusaders captured Jerusalem in 1099 they massacred every man, woman, and child in the city until the streets ran ankle deep with the blood.

This is a favorite used to demonstrate the evil nature of the Crusades. Most recently, Bill Clinton in a speech at Georgetown cited this as one reason the United States is a victim of Muslim terrorism. (Although Mr. Clinton brought the blood up to knee level for effect.) It is certainly true that many people in Jerusalem were killed after the Crusaders captured the city. But this must be understood in historical context. The accepted moral standard in all pre-modern European and Asian civilizations was that a city that resisted capture and was taken by force belonged to the victorious forces. That included not just the buildings and goods, but the people as well.

That is why every city or fortress had to weigh carefully whether it could hold out against besiegers. If not, it was wise to negotiate terms of surrender. In the case of Jerusalem, the defenders had resisted right up to the end. They calculated that the formidable walls of the city would keep the Crusaders at bay until a relief force in Egypt could arrive. They were wrong. When the city fell, therefore, it was put to the sack. Many were killed, yet many others were ransomed or allowed to go free. By modern standards this may seem brutal. Yet a medieval knight would point out that many more innocent men, women, and children are killed in modern bombing warfare than could possibly be put to the sword in one or two days.

It is worth noting that in those Muslim cities that surrendered to the Crusaders the people were left unmolested, retained their property, and allowed to worship freely. As for those streets of blood, no historian accepts them as anything other than a literary convention. Jerusalem is a big town. The amount of blood necessary to fill the streets to a continuous and running three-inch depth would require many more people than lived in the region, let alone the city.
