The term Treaty of Berlin is often used for the separate post-World War I peace accord of August 25, 1921 between the United States and Germany following the U.S. Senate's rejection of parts of the 1919 Treaty of Versailles and Warren G. Harding's defeat of League of Nations advocate James M. Cox in the 1920 presidential election.
