Answer:
several factors: Treaty of Versailles leading to a short lived Weimar Republic
Step-by-step explanation:
Germany's economic crisis owned much to the results of the conditions created by the Treaty of Versailles. The debt that was to be paid for war reparations turned the situation into an internal chaos. Often leaders profit from the strong desire for order and a strong state. The deutsche Mark lost its purchasing power so people was unable to earn for living, surviving was not possible even if work and labor were intensified. This is known as the hyperinflation of 1924.
The poorest and critical conditions lead to spread of communism not only in Germany but here it was a real threat just as some years caused the tookover by the Bolsheviks with the Tzar. Conservatives and politicians then preferred the national socialism of Hitler as an agressive approach under the prevailing circumstances.
In general the people embraced a leader full of charisma, that promoted a new future for those who long wanted to restablish to prewar order and also were naive to believe that the rearmy of the country and the industries would indefinetly keep making this growth sustainaible in the long term.
