Kellogg-Briand Pact Signed to Renounce War
Following the devastation of World War I, French Foreign Minister Aristide Briand proposed a bilateral agreement with the United States to outlaw war. U.S. Secretary of State Frank B. Kellogg expanded the idea into a multilateral treaty. On August 27, 1928, representatives from fifteen nations, including Germany, France, the United Kingdom, Italy, Japan, and the United States, signed the General Treaty for Renunciation of War as an Instrument of National Policy in Paris. The pact committed signatories to settle disputes by peaceful means and eventually attracted dozens more adherents. Though lacking enforcement mechanisms, it reflected widespread postwar idealism about collective security. The treaty entered into force in 1929 and remains technically in effect.
Why it matters: The pact symbolized the era's hope for lasting peace and influenced later international law, including the United Nations Charter. It provided a legal basis for prosecuting aggression in World War II tribunals despite its limitations. The agreement highlighted tensions between idealistic diplomacy and the realities of power politics in the interwar period.
