The fear in Germany prior to World War II was the Communists. And prior to World War II, Germany sent men and equipment to fight against the Communists in the Spanish Civil War. The NSDAP, or National Socialist Democratic Workers’ Party, is the full name of the abbreviated NAZI. It was a social and political movement designed to rekindle national pride. It included ceremonies to revive awareness of ancient Germanic peoples and the purity of the Aryan race. I have seen photos of German wartime burials that included crosses and priests. After the Germans attacked Russia, a German propaganda poster showed Christ on the cross and warned the people that the Communists denied this truth. In an area called the Katyn forest, the Russians murdered thousands of Polish officers, soldiers, priests and others. They blamed it on the Germans. The Germans alerted the Red Cross who came to examine the mass grave. Eventually, it was revealed that the Russians were the culprits.
The Russians killed or starved millions of people. Officers who did not obey were shot or sent to labor camps.
To call them religions is not accurate. They were political, social and economic movements.
