Martin Luther (1483-1546) founded a new Christian faith, Protestantism, in the 16th century. He had been an ordained priest, but disputed Church policy with respect to the sale of indulgences (a partial remission of the punishment for a sin). Once a supporter of the Jews, he was frustrated by their unwillingness to embrace his own religion. Martin Luther became one of the most intensely bitter anti-Semites in history. His writings described Jews as the anti-Christ, worse than devils. Jews were poisoners, ritual murderers, and parasites, he preached, and they should be expelled from Germany. His view was that synagogues should all be burned to the ground, and all Jewish books should be seized.
