John Maynard Keynes 
Economic Consequences of Peace 

Generally regarded as the most influential social science treatise of the 20th century, this work by legendary economist John Maynard Keynes is relevant reading even today for anyone who wants to understand international economics and foreign affairs. First published in 1919, The Economic Consequences of Peace created an intense and immediate controversy for its brazen criticism of world leaders and the Treaty of Versailles that ended World War I. Keynes argued that as a blueprint for peace, it was destined to create tension and conflict ahead…and history proved him right when world war broke out again within a generation. The popularity of this key work, and its place in history, helped cement Keyness status as one of the 20th centurys principal economists.
