The Economic Consequences of the Peace was written and published by John Maynard Keynes. After World War I, Keynes attended the Versailles Conference as a delegate of the British Treasury and argued for a much more generous peace. It was a best seller throughout the world and was critical in establishing a general opinion that the Versailles Treaty was a "Carthaginian peace." It helped to consolidate American public opinion against the treaty and involvement in the League of Nations.
