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.[1] It was founded in 1917 after the Russian Revolution and with Russia's withdrawal as an ally imminent.[2] 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.
