The first crusade wasn't until 400 years after Islamic hordes took Jerusalem and had made many offensive incursions into Europe and Anatolia. Good thing too or the whole west would be in the dark ages still had the Arabs taken over. It's funny you have to refer back to the year 1095 to push your crap...I just have to open yesterday's paper to see Muslims rampaging. The crusades were a response to Islamic aggression.
