The Reichstag Fire:

The day after the fire, Hitler persuaded President Hindenburg to issue a decree entitled, "For the Protection of the People and the State." Justified as a "defensive measure against Communist acts of violence endangering the state," the decree suspended the constitutional guarantees pertaining to civil liberties:

Two weeks after the Reichstag fire, Hitler requested the Reichstag to temporarily delegate its powers to him so that he could adequately deal with the crisis. Denouncing opponents to his request, Hitler shouted, "Germany will be free, but not through you!" When the vote was taken, the result was 441 for and 84 against, giving Hitler the two-thirds majority he needed to suspend the German constitution. On March 23, 1933, what has gone down in German history as the "Enabling Act" made Hitler dictator of Germany, freed of all legislative and constitutional constraints.

For their part, the German people quickly accepted the new order of things. Keep in mind that the average non-Jewish German was pretty much unaffected by the new laws and decrees. As long as a German citizen kept his head down, worked hard, took care of his family, sent his children to the public schools and the Hitler Youth organization, and, most important, didn’t involve himself in political dissent against the government, a visit by the Gestapo was very unlikely.

Describing how the average German adapted to the new order, Shirer writes,

The overwhelming majority of Germans did not seem to mind that their personal freedom had been taken away, that so much of culture had been destroyed and replaced with a mindless barbarism, or that their life and work had become regimented to a degree never before experienced even by a people accustomed for generations to a great deal of regimentation.... The Nazi terror in the early years affected the lives of relatively few Germans and a newly arrived observer was somewhat surprised to see that the people of this country did not seem to feel that they were being cowed.... On the contrary, they supported it with genuine enthusiasm. Somehow it imbued them with a new hope and a new confidence and an astonishing faith in the future of their country.
