How did world war 1 contribute to the rise of Adolf Hitler and the nazi party in Germany

The defeat of Germany in World War I led to a sense of resentment in Germans. After the war the Weimar Republic was created, but its constitution was very weak. Many wealthy businessmen were afraid of the new phenomenon of communism, so they started backing Hitler, who used these moneys for his Nazi propaganda.

Explanation: After the defeat in the WWI, Germany was, according to the Treaty of Versailles, guilty of war damage, had to reduce its weapons, pay war damages, and be marked as the main culprit for war. All of this in combination with the Great Depression caused the economic crisis in Germany and the sense of humiliation among the Germans. Under such conditions, Hitler, who in his campaigns promised to launch the German economy and raise national pride, took advantage of such a suitable ground for launching a Nazi idea that was usually well accepted by the people in such conditions. There were those who supported his work for the dangers of communism, but also the broad masses saw the way out in his promises.
