The Crusades were no longer a conflict within the history of wars. They were a clash between two worldviews: Christianity and Islam. The beginning of the Crusades, unlike other wars, was based on the principles of just war. This work gave a summary of the origins of just war and Islam. Then he showed that the Church of Rome applies these principles in some cases. One such case was the Crusades.
