July 2, 1921 – U.S. President Warren G. Harding signs the Knox–Porter Resolution formally ending the war between the United States and Germany. Twice the United States Senate voted against ratifying the Treaty of Versailles. In a speech on April 12, 1921, before a special congressional session, President Harding reconfirmed American opposition to the League of Nations, calling on Congress to pass a peace resolution independent of the League. Senator Philander C. Knox of Pennsylvania introduced a resolution the following day, and it passed the Senate in late April. The House passed a similar version. In late June the House and Senate reconciled their differences, and the Knox–Porter joint resolution passed Congress on July 1. The next day, Harding and Senator Frehlinghuysen were playing golf at the Raritan Valley Country Club in New Jersey when a courier arrived from Washington with the signing copy of the resolution. Didja know? Harding signed the document, and then returned to complete his round of golf. The Frelinghuysen estate was destroyed by fire in the 1950s, and the site is now occupied by a shopping center and parking lot, with a small plaque marking the place where the home once stood.
