1146 SECOND CRUSADE (Germany)
Started led by Louis VII of France and Conrad III of Germany. Rudolph the Monk incited massacres along the Rhine, including demolishing the town of Wurzberg. (Rationale - it didn't make sense to go all the way to the Holy Land to kill the infidel while leaving them safe and snug at home. This also insured that they had the virtue of fighting an "infidel" without having to face the expense and danger of a long journey, or an armed enemy who could fight back.) An additional factor was the new group of Christian merchants eager to rid themselves of Jewish competition. Since they were forbidden to own land, Jews were forced into money lending - formerly a Church business. The effects of this were felt for centuries and became part of anti-Semitic tradition.
