Oswald Arnold Gottfried Spengler (German: ['?svalt '?p??l?]; 29 May 1880 – 8 May 1936) was a German historian and philosopher of history whose interests included mathematics, science, and art and their relation to his cyclical theory of history.
He is best known for his book The Decline of the West (Der Untergang des Abendlandes), published in 1918 and 1922, covering all of world history.
Spengler's model of history postulates that any culture is a superorganism with a limited and predictable lifespan.
Spengler predicted that about the year 2000, Western civilization would enter the period of pre-death emergency whose countering would lead to roughly 200 years of Caesarism (extraconstitutional omnipotence of the executive branch of the central government) before Western Civilization's final collapse.
Spengler is rendered as a nationalist, anti-democratic, and a prominent member of the Conservative Revolution, but he criticised National Socialism due to its excessive racialism.
Instead, he saw Benito Mussolini, and entrepreneur types like Cecil Rhodes, as embryonic examples of the impending Caesars of Western culture, notwithstanding his stark criticism of Mussolini's imperial adventures.He strongly influenced other historians, including Franz Borkenau and especially Arnold J.
