The Supreme War Council was a central command based in Versailles that coordinated the military strategy of the principal Allies of World War I: Britain, France, Italy, the United States, and Japan. It was founded in 1917 after the Russian Revolution and with Russia's withdrawal as an ally imminent. The council served as a second source of advice for civilian leadership, a forum for preliminary discussions of potential armistice terms, later for peace treaty settlement conditions, and it was succeeded by the Conference of Ambassadors in 1920.

The Grand Quartier Général was the general headquarters of the French Army during the First World War. It served as the wartime equivalent of the Conseil supérieur de la guerre and had extensive powers within an area defined by the French parliament. The GQG was activated by parliament on 2 August 1914, after the violation of French borders by German military patrols, and remained in existence until 20 October 1919.
