The Nazi state after 1934 idolised Hitler as its Führer ("Leader"), centralising all power in his hands.
Nazi propaganda, led by Josef Goebbels, centred on Hitler and was effective in creating what historians have called the "Führer Myth" – that the Leader was all-wise and that any mistakes or failures would always be caused by others, and would be corrected when brought to his attention.
It was important for the new and inexperienced Nazi Party to manufacture the 'Führer cult' to ensure the attainment of Nazi political ends. The Nazis used new techniques of propaganda to exploit and build on the beliefs, phobias, and prejudices of the time in Germany. The weakness of the Kaiser Wilhelm II in the Great War, the failure of democracy in the Weimar period, and the dominance of Jews in the financial sector; all these led to easy creation of the Myth. People were looking for exactly the situation described by Goebbels, even though it was based on lies and exaggerations.
In 1929, Goebbels said [shouted], "We believe that Fate [sometimes translated as Heaven, History, or God] has chosen him to show the way to the German people. Therefore we greet him in devotion and reverence, and can only wish that he may be preserved for us until his work is completed." He presented Hitler as a demigod; or maybe as a Teutonic god in his own right.
Propaganda often presented Hitler as Wotan, the principal Teutonic god of wisdom, prophecy, war, victory, and hunting. He sometimes dressed in rustic costume when in public, to strengthen this association: lederhosen, feathered cap, shepherd's shawl. And the influence of Richard Wagner's music was increased, since it referred specifically to the ancient gods and their warlike ways. [As a matter of interest, Wotan is known also in Norse mythology as Odin or Woden, after whom Wedneday is name.]
In reality, Hitler had a narrow range of interests and limited understanding of world affairs. Decision-making was diffused among overlapping feuding power centres in his administration. On some issues he was passive, simply agreeing to pressures from whoever had his ear at the time.
All the historical and medical evidence available now shows that Hitler was an inadequate human being; incapable of love or affection unless linked to some perversion or other. He had great persuasive powers, a natural demagogue and liar, but unwilling to consider any proposal made to him that was not presented as his own.
