Hey there!
The first law was passed by the Nazis in an event called the "Enabling Act of 1933." The first two laws were called the Reichstag and the Reichsrat. It was supported by many Nazi followers, questionably by real support or by fear. It was eventually signed by Paul von Hindenburg on the same day it was introduced. This was around the time of March.
This didn't just put Hiter's ideologies into effect. It gave him sovereignty over everywhere he ruled, and this is arguably one of the "boosters" that gave him even more power.
Hope this helps!
