The Economic Consequences of the Peace (1919) was a best seller throughout the world, published by John Maynard Keynes. Keynes attended the Versailles Conference as a delegate of the British Treasury and argued for a much more generous peace with Germany. The book was critical in establishing a general worldwide opinion that the Versailles Treaty was a brutal and unfair peace towards Germany. It helped to consolidate American public opinion against the treaty and involvement in the League of Nations. The perception by much of the British public that Germany had been treated unfairly in turn was a crucial factor in public support for appeasement. The success of the book established Keynes' reputation as a leading economist especially on the left.
