In page Oswald Spengler:

"

When the first volume of The Decline of the West was published, it was a wild success.[a] Spengler became an instant celebrity.[3] The national humiliation of the Treaty of Versailles (1919), followed by economic depression in 1923 and hyperinflation, seemed to prove Spengler right. Decline comforted Germans because it could be used as a rationale for their diminished pre-eminence, i.e. due to 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.[citation needed]
