Der Untergang des Abendlandes
When "The Decline of the West" was published in the summer of 1918, it was a wild success. The national humiliation of the Treaty of Versailles (1919) and later the economic depression around 1923 fueled by hyperinflation seemed to prove Spengler right. It comforted Germans because it seemingly rationalized their downfall as part of larger world-historical processes. The book met with wide success outside of Germany as well, and by 1919 had been translated into several other languages. Spengler declined a subsequent offer to become Professor of Philosophy at the University of Göttingen, saying he needed time to focus on writing.
