Effects of the Crusades
The Crusades kept all Europe in a tumult for two centuries, and directly and indirectly cost Christendom several millions of lives (from 2,000,000 to 6,000,000 according to different estimates), besides incalculable expenditures in treasure and suffering. They were, moreover, attended by all the disorder, license, and crime with which war is always accompanied. On the other hand, the Holy Wars were productive indirectly of so much and lasting good that they form a most important factor in the history of the progress of civilization.
