Judaism

Judaism is the world's oldest monotheistic religion. It is practiced by the Jews.

Judaism in Ruled Britannia
Jews were blamed for the death of Jesus Christ by Christians, and the practice of the religion was discouraged or flat-out persecuted in both Catholic and Protestant countries.

Judaism in World War
Judaism could not be openly practiced in the Greater German Reich for fear that it would expose its practicioner as an ethnic Jew rather than because the Nazi Party found the faith itself objectionable. Among Jews who were persecuted by the Germans, devotion to the religion was encouraged, and after the Race took over Poland, the faith was practiced openly by a large and vibrant faith community.
