Pope Urban II's speech has an impact larger than even he expects. Throughout Western Europe, news of his speech, news of his call to go and retake the Holy Land to fight against this despised and base race, the Muslims, takes hold. And before the pope is even able to organize a formal army, you have someone by the name of Peter the Hermit lead what's called the People's Crusade in 1096. And this is often considered the first part of the First Crusade. As they march through the Rhineland in what is now Germany, they massacre Jews, several thousand, calling them Christ killers on their way to the Holy Land. And this is a theme that you will see throughout the Crusades. Even though the Crusaders ostensibly were there to help the Byzantines, ostensibly to take back the Holy Land, as they travel through foreign lands, they often wreak a lot of havoc, even sometimes on the Byzantines themselves.
