Oswald Spengler (1880–1936) was a German philosopher and historian best known for his work "The Decline of the West" ("Der Untergang des Abendlandes"). Published in two volumes in 1918 and 1922, this influential work presents a cyclical theory of history, where civilizations rise and fall in a predictable manner akin to the life cycle of living organisms.
