lol. I seem to have hijacked the thread into a historical debate.
I won't argue that most of the nobility who went crusading were looking for something, either eastern lands or spoils of war, or most importantly, status back home. That's why they generally tended to go, conquer, and go home again. But on the other hand, there were TONS of believers who stayed behind, who really were convinced that the crusades were their salvation, their only hope. The Knights Templar are a good example, as were the other orders who formed back then. (knights of St. John, knights of St. George, etc.) And yes, the pope was motivated by lots of things, but he would have had no excuse to make war if Jerusalem were not a holy land, and also he had to be able to justify any act through the Bible, and had to search for ways to allow leaders to conduct a religious war. That said, the leaders of the lands of Europe were fighting a 'Holy' crusade. And if you look at the descriptions by Muslim leaders of the crusaders, they were filled with religious zeal. Not my descriptions, I'm getting this from the readings I'm doing for my medieval history class.
And while it is true that it was not purely a 'Muslim' thing, it wasn't really an 'Arab' thing. The writings by people such as the abbot Suger and others make it clear that they are fighting 'infidels' and 'pagans.' *read Jews and Muslims, because, again, the Jews definitely got it good in the crusades, much like every other time period.* Perhaps the Pope and some of the nobility were going for spoils, but that didn't mean it wasn't a religious crusade. The readings by the Muslims who wrote about it made it clear that the population of Muslims were highly cultured, and that the Europeans were backwards idiots who were driven by religion. Most of those who stayed actually appreciated the cultural aspects of the region, things like music and medicine and math. They just wanted to drive out the 'pagans'.
Good example of the artistic/cultural appreciation of the Europeans, a crusader learning to play the guitar from a Muslim. (Image care of wikipedia) And one last side note, the fact that the Jews got targeted really tends to uphold the fact that it was a religious war, and not a cultural one. If they were only targeting Arabs, those Jews who were a different ethnic background wouldn't have been targeted, but they were, due to their religious make up. It wasn't anti-Arab war, it was Christians vs. Non-Christians war.
