After being leader of the Nazi party, he acquired power in Germany in 1933 as the Federal Chancellor. The Parliamentary and judicial systems, which were based upon equality in the law, were thereby eliminated.
The only party left was the Nazi party, which functioned as an obedient executive branch to carry out Hitler's will. Competing parties were dissolved.
He was as treacherous and unreliable towards his own as he was in his external politics. His record became a series of bluffs, lies and broken agreements, as for example, in the peace treaty with the Soviets. But in Nazi propaganda, he was portrayed as a friend of children, and as the unique leader of the people, "der Führer".
Caught off-guard by Hitler's brashness, the European superpowers for all too long gave in to his demands with ill-fated consequences. This cost all of humanity untold suffering during the almost 6 years of the second world war. In addition, at least 6 million Jews lost their lives in Hitler's concentration camps. He blamed the Jews as being the root of all evil on earth.
Note: Before we go further, we will take a look at the Bible's summary of the world empires. The information which the Apostle John received during the time of the Roman empire concerning the 8 world kingdoms was this: Five have already fallen, the sixth reigns currently and the seventh will come, but his period of rule will be short (Hitler's 12 years).
The scarlet red beast is itself the eighth king. He has reigned once earlier as one of the seven. (Revelation 17:3, 17:10-11) Is this the spirit of the Roman empire or that of the Nazi regime which will reappear?
