Kellogg–Briand Pact

Kellogg–Briand Pact (1928)

The Kellogg–Briand Pact (or Pact of Paris, officially General Treaty for Renunciation of War as an Instrument of National Policy^[1]) is a 1928 international agreement in which signatory states promised not to use war to resolve "disputes or conflicts of whatever nature or of whatever origin they may be, which may arise among them".^[2] Parties failing to abide by this promise "should be denied of the benefits furnished by this treaty".

It was signed by Germany, France, and the United States on 27 August 1928, and by most other nations soon after. Sponsored by France and the U.S., the Pact renounces the use of war and calls for the peaceful settlement of disputes. Similar provisions were incorporated into the Charter of the United Nations and other treaties and it became a stepping-stone to a more activist American policy.^[3] It is named after its authors, United States Secretary of State Frank B. Kellogg and French foreign minister Aristide Briand.

After negotiations, the pact was signed in Paris at the French Foreign Ministry by the representatives from Australia, Belgium, Canada, Czechoslovakia, France, Germany, British India, the Irish Free State, Italy, Japan, New Zealand, Poland, South Africa, the United Kingdom^[4] and the United States. It was provided that it would come into effect on 24 July 1929.

By that date, the following nations had deposited instruments of definitive adherence to the pact: Afghanistan, Albania, Austria, Bulgaria, China, Cuba, Denmark, Dominican Republic, Egypt, Estonia, Ethiopia, Finland, Guatemala, Hungary, Iceland, Latvia, Liberia, Lithuania, the Netherlands, Nicaragua, Norway, Panama, Peru, Portugal, Romania, the Soviet Union, the Kingdom of the Serbs, Croats, and Slovenes, Siam, Spain, Sweden, and Turkey. Eight further states joined after that date (Persia, Greece, Honduras, Chile, Luxembourg, Danzig, Costa Rica and Venezuela^[5]) for a total of 62 signatories. In 1971, Barbados declared its accession to the treaty.^[6]

In the United States, the Senate approved the treaty overwhelmingly, 85–1, with only Wisconsin Republican John J. Blaine voting against.^[7] While the U.S. Senate did not add any reservation to the treaty, it did pass a measure which interpreted the treaty as not infringing upon the United States' right of self-defense and not obliging the nation to enforce it by taking action against those who violated it.

Effect and legacy

Historian Harold Josephson notes that the Pact has been ridiculed for its moralism and legalism and lack of influence on foreign policy. He argues instead that it led to a more activist American foreign policy. Its central provisions renouncing the use of war, and promoting peaceful settlement of disputes and the use of collective force to prevent aggression, were incorporated into the UN Charter and other treaties. Although civil wars continued, wars between established states have been rare since 1945, with a few exceptions in the Middle East.^[8]

Mockery of the Pact during the Paris Carnaval in 1929

The 1928 Kellogg–Briand Pact was concluded outside the League of Nations, and remains in effect.^[9] One month following its conclusion, a similar agreement, General Act for the Pacific Settlement of International Disputes, was concluded in Geneva, which obliged its signatory parties to establish conciliation commissions in any case of dispute.^[10]

As a practical matter, the Kellogg–Briand Pact did not live up to its aim of ending war or stopping the rise of militarism, and in this sense it made no immediate contribution to international peace and proved to be ineffective in the years to come.^[11] Moreover, the pact erased the legal distinction between war and peace because the signatories, having renounced the use of war, began to wage wars without declaring them as in the Japanese invasion of Manchuria in 1931, the Italian invasion of Abyssinia in 1935, the Spanish Civil War in 1936, the Soviet invasion of Finland in 1939, and the German and Soviet invasions of Poland.^[12]

The pact is an important multilateral treaty because, in addition to binding the particular nations that signed it, it has also served as one of the legal bases establishing the international norms that the threat^[13] or use of military force in contravention of international law, as well as the territorial acquisitions resulting from it,^[14] are unlawful.

Notably, the pact served as the legal basis for the creation of the notion of crime against peace. It was for committing this crime that the Nuremberg Tribunal and Tokyo Tribunal tried and executed the top leaders responsible for starting World War II.

The interdiction of aggressive war was confirmed and broadened by the United Nations Charter, which provides in article 2, paragraph 4, that "All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations." One legal consequence of this is that it is clearly unlawful to annex territory by force. However, neither this nor the original treaty has prevented the subsequent use of annexation. More broadly, there is a strong presumption against the legality of using, or threatening, military force against another country. Nations that have resorted to the use of force since the Charter came into effect have typically invoked self-defense or the right of collective defense.
