When he first got into politics the people and news media considered him a joke. His next time he was considered a raving lunatic. Some of his ravings was telling the people they were the great people whose blood was being contaminated by inferior people. Although not religious he convinced the people that non christian people are bad for the country. He incited riots by his words but did not directly order them so he could have plausible deniability. After gaining control he required open shows of loyalty to him. He attacked his enemies with his rants and his words influenced his sycophants to deal with them.
Those are words from a 1996 documentary using films made in the 1930s and 1940s of Adolf Hitler’s rise and end. A saying in history classes is that history tends to repeat itself. History is full of examples throughout the centuries.
