This investigation is concerned with the role played by the illusions of security, Bolshevism, and American innocence in the making of the Versailles Treaty of 1919. The main sources used in this thesis were the U.S. State Department publications The World War and The Paris Peace Conference and Paul Mantoux's Proceedings of the Council of Four. The drafting of the Versailles Treaty is approached chronologically with special emphasis accorded the problems emanating from the questions of Russia and the Rhine. The study concludes that the peacemakers were manipulated by the illusions of security, Bolshevism, and American innocence.
