It's also important to say that this is not just a disease of the poor. Because of the habits of the times, the way that people lived, even the rich, and the way that the fleas were transmitted on these trade routes along clothing lines, even fine linens, this would reach the upper class as well. And even though the poor had a higher rate, probably because they were congregated together in smaller spaces, this didn't spare all the rich people. In fact it was monasteries that were probably the most susceptible to the disease because priests going to give last rites, bringing that back amongst an isolated community, and it's spreading quite quickly with some monasteries experiencing a 100% rate of death. Now of course you couldn't have a plague, you couldn't have something horrible happen if you didn't have somebody to blame. We all know that to be true. It's got to be someone's fault, right?
