Conference of Ambassadors

The Conference of Ambassadors of the Principal Allied and Associated Powers was an inter-allied organization of the Entente in the period following the end of World War I. Formed in Paris in January 1920 it became a successor of the Supreme War Council and was later on de facto incorporated into the League of Nations as one of its governing bodies. It became less active after the Locarno Treaties of 1925 and formally ceased to exist in 1931 or 1935.

The Conference consisted of ambassadors of Great Britain, Italy, and Japan accredited in Paris and French minister of foreign affairs. The ambassador of the United States attended as an observer because the U.S. was not an official party to the Treaty of Versailles. French diplomat René Massigli was its secretary-general for its entire existence. It was chaired by foreign minister of France (among them Georges Clemenceau, Raymond Poincaré, Aristide Briand).

The Conference was formed to enforce peace treaties and to mediate various territorial disputes among European states. Some of the disputed regions handled by the Conference included Cieszyn Silesia (between Poland and Czechoslovakia), Vilnius Region (between Poland and Lithuania), Klaipėda Region (between Germany and Lithuania), and the Corfu Incident (between Italy and Greece). One of its major territorial decisions was made on 15 March 1923, in recognizing the eastern borders of Poland created following the Polish–Soviet War of 1920. The Conference of Ambassadors of the Principal Allied and Associated Powers was appointed by the League of Nations to take charge of the Greek/Albanian border dispute that turned into the Corfu Incident of 1923.
