The period following the Great War, was total chaos. In 1918/19 Spanish Influenza killed 50 to 100 million people, a modern Black Death. With the same results, shortage of labour , food, work, infrastructure damaged, and Germany very near to Communist take over. England survived relativly well. America was coming to prominence , with a lot of links to what was left of the German economy, then came the Wall Street Crash and depression. Hitler was promosing a New Dawn, and he was not tainted with the stain of the Old Gaurd. Bear in mind at that time Germany had only existed as a unified state for about 50 years, and up till then had been an autocratic monoarchy. There was no tradition of Democracy, and franckly I doubt the average German citizen at the time cared. An empty belly calls very loud. Bread and Circusis, which the Nazi supplied would have looked very good, and the word Socialsit in the name implies a care about the well being of the avaerage person. You can add the baleful influence of Woodrow Wilson and his 14 point plan and his hunger for Imortallity. Hitler was an opertunist and attracted the right backers, what wa sleft of the Junker class who thought they'd use and dump him. Wrong wern't they!
