The impact Great Depression and the failure of successive Weimar governments was ultimately a large step for the Nazis to come to power. Germany, even during 1924-29 were unstable as they were reliant on foreign loans and now couldn't repay them as well as meet their reparation payments. Government after government adopted a deflationary policy, to contract the economy, and the economy further contracted, 6 million unemployed in 1932. The Nazis took advantage of this, they promised to fix the problems, when they ran for the Reichstag and when Hitler ran for president, Hitler said in one particular poster,' Adolf Hitler will provide work and bread'. Hitler was seen as having the strong leadership Germany needed but no one else possessed.
But even throughout 1924-29 there were actions taken by the governments of those days that were intended to further take away germany's pre WW1 prestige such as joining the League of Nations (the very organisation that'd imposed the Treaty of Versailles on the German nation) and openly participating in its activities. Those actions always made the conservative elite upset but the depression was the final straw for them to turn to the Nazis - because they promised to fix those problems other Weimar governments could or would not.
