Which pact called for the renunciation of war as a national policy?

The Kellogg-Briand Pact, signed in 1928, is the treaty that called for the renunciation of war as a national policy. It was an international agreement in which signatory states pledged not to use war to resolve conflicts or disputes, aiming to promote peace following the devastation of World War I. The signatories hoped to establish a framework for peaceful international relations and discourage military aggression.

The Kellogg-Briand Pact reflected a growing sentiment in the post-war world toward disarmament and the resolution of conflicts through diplomacy rather than military means. Although it ultimately proved to be ineffective in preventing future wars, it represented a significant commitment to the principle of peace and laid the groundwork for later international initiatives aimed at conflict resolution.
