John Maynard Keynes wrote this polemical attack on the Treaty of Versailles immediately after participating in the Paris Peace Conference as a British Treasury representative. He argued that the reparations imposed on Germany were economically impossible to pay and would produce political catastrophe. Keynes prophesied that attempts to extract punitive payments would impoverish Germany, destabilize central Europe, and ultimately threaten the peace the treaty was meant to secure. The book was an immediate sensation, shaping views of the treaty and Keynes's own reputation. Later scholarship has complicated Keynes's analysis—Germany perhaps could have paid more than he thought, and treaty enforcement was lax—but his influence on how Versailles was understood was immense. The book remains valuable both as historical document and as example of how economic analysis enters political debate. Keynes wrote brilliantly, mixing technical argument with devastating portraits of the leaders at Paris, establishing a style of public intellectual engagement that influenced subsequent generations.
