that crusading was just an opportunity for enrichment with sadistic dividends, is wrong. A handful of princes created new fiefdoms and a few Crusaders made their careers, whereas the costs were punishing and many lives and fortunes were lost in this quixotic and risky but pious enterprise. A spirit was abroad that is hard for modern people to grasp: Christians were being offered the opportunity to earn the forgiveness of all sins. In short, these warrior-pilgrims were overwhelmingly believers seeking salvation on the battlements of Jerusalem.
