I'm not confident I can write an essay, but I can certainly give you the key points. First of all, on the night of the Reichstag fire (27th Feb 1933), the Nazi's blamed Marinus Van Der Lubbe (a dutch communist arsonist) for the fire. This was convenient for Hitler as he was trying to turn everyone against the communists because it'd lead everyone towards him. Next, during the event of the Enabling Act (23rd march 1933), the Nazi's barricaded exits of the Kroll Opra House so that people couldn't leave and had to follow Hitler's ideals. Thanks to the Nazi's use of fear, violence, and intimidation, the Enabling Act was passed with 441 votes to 94. The Enabling Act was seen by many as the end of Democracy in germany, so the Nazi's played a very big part in Hitler's dictatorship over Germany. On the 2nd of May 1933, a policy called the Gleichstchtug was introduced in which Hitler/the Nazi's could interfere with German citizens' private lives, like posts, phone calls, etc. All trade unions were banned, and only one trade union was introduced, which was, of course, completely run and filled by Nazis (German Labour Front, or, the DAF- Deutsche Arbeitsfront)
i apologise if this isn't what you need or this is too late, but i hope I helped even a little!
