A multilateral agreement condemning war. It grew out of a proposal by the French Premier, Aristide Briand, to the US government for a treaty outlawing war between the two countries. The US Secretary of State, Frank B. Kellogg, proposed a multilateral treaty of the same character. In August 1928 15 nations signed an agreement committing themselves to peace; the USA ratified it in 1929, followed by a further 46 nations. The failure of the Pact to provide measures of enforcement nullified its contribution to international order.
