"It appears an extraordinary thing to me, that since there is such a diabolical spirit in the depravity of human nature, as persecution for difference of opinion in religious tenets, there never happened to be any inquisition, any auto da fe, any crusade, among the Pagans."

In most cases, obviously, soldiers fought because a government drafted them and gave them a rifle. At every point too, we see the role of nationalistic sentiment, commercial rivalries, and simple greed. But can we ever separate out such motives from the religious? Was that not also true of the medieval crusades?
