The Nazis became popular due to the impact of the Great Depression, weaknesses of the Weimar Republic, and strength of the Nazi Party.
In 1929, the Wall Street Crash occurred in the USA, causing banks to lose billions of dollars.
The Great Depression affected Germany primarily due to unemployment.
US banks stopped loans to Germany, causing German industries to lose finance and lay off workers.
By 1932, 40% of workers in Germany were unemployed.
The German government had no money, so it reduced unemployment benefits.
The combination of factors led to families suffering and losing faith in democracy.
The failure of the Weimar Republic was due to the inability of the government to solve the problem of unemployment.
Heinrich Brüning became the Chancellor of the Weimar Republic in March 1930, just after the Great Depression was taking hold of the global economy.
Brüning introduced policies to cut wages, aiming to increase employment.
The public was unhappy with Brüning's policies as they saw their wages falling if they were employed and their benefits and social security falling if they were unemployed.
The parliament and Reichstag resisted Brüning's policies, so he used Article 48 to ignore parliament and bypass the government.
Brüning's reliance on 'Article 48' set a precedent for Hitler to use Article 48 after the Reichstag Fire.
The next step after the Reichstag Fire was Hitler's use of the Enabling Law.
