The two main religions in Germany at this time were Catholicism and Protestantism.  Southern Germany, including Munich, is traditionally Catholic, while the northern states are Lutheran. 

The Nazi Party often cited the work of protestant hero Martin Luther to further their nationalist cause; they particularly exploited his strong anti-Jewish opinions.
