When the Germans lost WWI they had the treaty of Versalie (not spelled correct) imposed on them and it restricted much of what they could do in the international market which made the depression more severe on them. Also little if any of WWI was fought on German soil and the German media did not tell the real story of the battles that happened on the front. Hitler and others said that the Germans were stabbed in the back by the people in power at the time and he had a better plan. He also said he would give employment to a country that had extremely high unemployment and very high inflation and was ruled by very old rich people who did not have a clue. All this together with other items helped put Hitler in power. IF you have no money, no job, are hungry, and there is no welfare programs then you will sit up and listen to a person who offers you some hope for better times.
Hitler was also an excellent speaker that helped him alot. In the 1920's the communist party was very strong in Germany and it could have gone in that direction as easily but for a lack of a good speaker in the communist party. You have to remember that in that time period all there was were newspapers,some radio,and public meetings with a speaker and lots of people who were hungry and restless for a change.
