Geneva Disarmament Conference.

After World War I, world leaders sought to reduce the number of available armaments to avoid another catastrophic war. They successfully negotiated naval treaties at the Washington Naval Conference in 1921-1922 and the London Naval Conference in 1930. The high cost of arms races and the economic difficulties of the Great Depression greatly contributed to the call for arms reductions. President Herbert Hoover strongly supported the idea of a disarmament conference for economic reasons.
