John Maynard Keynes 
The Economic Consequences of the Peace [EPUB ebook] 

In 1919, Keynes participated in the negotiations of World War I’s armistice. He strongly disagreed with terms of reparation imposed on Germany, arguing in this controversial book that German impoverishment would threaten all of Europe. This prophetic view of the European marketplace in the early 20th century represents a much-studied landmark of economic theory.
