Answer:
On the 31 January 1933, Hitler, conscious of his lack of a majority in the Reichstag, immediately called for new elections to try and strengthen his position. The Nazis aimed to increase their share of the vote so that they would have a majority in the Reichstag. This would allow them to rule unopposed and unhindered by coalition governments.
Over the next two months, they launched themselves into an intense election campaign.
On 27 February 1933, as the campaign moved into its final, frantic days, the Reichstag, the German Parliament building, was set on fire and burnt down. An atmosphere of panic and terror followed the event.
This continued when a young Dutch communist, Van der Lubbe was arrested for the crime.
The Nazi Party used the atmosphere of panic to their advantage, encouraging anti-communism. Göring declared that the communists had planned a national uprising to overthrow the Weimar Republic. This hysteria helped to turn the public against the communists, one of the Nazis main opponents, and 4000 people were imprisoned.
The day after the fire, Hindenburg signed the Emergency Decree for the Protection of the German People
