How did the Great Depression eventually change Germany politically?
It polarised the country and led to the rise of Nazism.
Germany felt the Great Depression more than most countries because of her huge financial penalties imposed by the Treaty of Versailles.
It was the perfect platform for Hitler to mobilise support against the perceived decadence and failure of the Weimar Republic, the humiliation of Germany by the victorious powers after World War 1 and the justification of his virulent and toxic anti-semitism; as he blamed the depression on Jewish bankers and financiers.
It was a crucial factor in bringing the Nazis to power, securing their defeat of the communist movement and leading to world War 2 with the loss of an estimated 70 million lives.
