The Washington Naval Conference, also called the Washington Arms Conference or the Washington Disarmament Conference, was a military conference called by U.S. President Warren G. Harding and held in Washington, D.C., from 12 November 1921 to 6 February 1922. Conducted outside the auspice of the League of Nations, it was attended by nine nations—the United States, Japan, China, France, Britain, Italy, Belgium, Netherlands, and Portugal[1][2]—regarding interests in the Pacific Ocean and East Asia. Soviet Russia was not invited to the conference. It was the first international conference held in the United States and the first arms control conference in history, and as Kaufman, 1990 shows, it is studied by political scientists as a model for a successful disarmament movement.

Held at Memorial Continental Hall in downtown Washington DC,[3] it resulted in three major treaties: Four-Power Treaty, Five-Power Treaty (more commonly known as the Washington Naval Treaty), the Nine-Power Treaty, and a number of smaller agreements. These treaties preserved peace during the 1920s but were not renewed in the increasingly hostile world of the Great Depression.
