What were the impacts of the crusades?

One impact would obviously be loss of life. Maybe that's not what your looking for, but there you go. Another would have been bankruptcy. After the 3rd crusade especially, Richard 'Lionheart' let himself get held for ransom by a duke who he had annoyed during the crusade, and the ransom was more than twice Britain's annual revenue! which Meant poor John, 'The worst king of England', had to raise the taxes which made everyone in England hate him, which leads on nicely to my next point - John's title as worst king of England, which personally I don't think he deserved, as lots of people would have been biased against him after the taxes, which would have made them more criticizing in their thoughts about him and in their records.
