The period from the destruction of the temple onward give rise to heavy persecution by Christians throughout Europe and Russia. Many groundless stories were spread, accusing Jews of ritual murder, the desecration of the Catholic host, and continuing responsibility for the execution of Jesus . Unsubstantiated rumors continue to be circulated today. In the 1930s and 1940s, Adolph Hitler and the German Nazi party drew on centuries of Christian-based anti-Semitism, and upon their own psychotic beliefs in racial purity. They organized the Holocaust, the attempted extermination of all Jews in Europe. About 6 million were killed in one of the world's largest examples of religious and racial intolerance.
