Adolf Hitler wrote in 1924: A State that refuses racial contamination must eventually rule the Earth. How could Hitler succeed in conquering Germany? Nothing predestines this mediocre student and failed artist to become dictator of Germany -- the Führer. The Great War of 1914-1918 turns him into a rabid racist, haunted by a vision and a mission: to save Germany. But the country is not particularly worried. Hitler is only considered a crank on the margins of German political life. The 1929 economic crisis will change all that.
