In the first half of the 20th century, a large reading public followed the comparative histories of (German) Oswald Spengler, (Russian-American) Pitirim Sorokin, and (British) Arnold J. Toynbee. Since the 1950s, however, comparative history has faded from the public view, and is now the domain of specialized scholars working independently.
