And it's important to note that there was a mass hysteria in many parts of Europe against the Jewish people and that in many cases they were massacred, they were burned alive. There were tens of thousands of Jews that were killed during this time period because it was claimed they were poisoning the wells with this disease. And it was also the thought that if they weren't getting it as much, they had something to do with it and that might be attributed to many of the customs of the Jewish faith like taking baths before the Sabbath, you know, washing your hands after you go to the bathroom, stuff like that. That's probably more of the culprit than, you know, the conspiracy of their putting it in the wells. So there's a lot of different effects that are going to ripple through Europe when you remove half of the population. And why don't we talk about those effects now because that's what you do in social studies. You talk about the causes and the effects.
