The first crusade is a fascinating mess of disease and death. Muslims oppressing Christians in the holy land, the pope says that anyone who goes down there to put them to rights gets a pardon for all of their sins on death and numerous other religious incentives, about 5 times the expected number turn up, including nobles and the poorest men and women from all across Europe. Death ensues and the resulting Latin states (Antioch, Jerusalem, and one other large one) barely last beyond the wars end. Ultimately fruitless but the source of a massive misconception about religious hatred
