It was not entirely calculated

“The origins of the annihilation of the German Jews were much more remote in time than the events of Krystallnacht. They are to be found in popular reactions to the dislocations that accompanied Germany’s belated but headlong rise as an industrial Power in the nineteenth century and in the growth of a virulent form of racist anti-Semitism in the Wilhelmine period, which remained latent until military defeat and economic collapse turned it into a potent rallying-cry for the rightist fanatics and demagogues who led the attack upon the Weimar constitution. The most gifted of these, Adolf Hitler, was also the one most obsessed with hatred and fear of the Jews.” – Gordon A. Craig, Germany 1866-1945
