Though believing in the racial superiority of Europeans over non-Europeans, the Fascist regime displayed diplomatic courtesy to non-Europeans. The regime held an alliance with Japan within the Tripartite Pact between Germany, Italy and Japan. Indian independence movement leader Mahatma Gandhi visited Italy in 1931 and was invited by Mussolini for a personal visit, providing Gandhi full diplomatic courtesy. Fascist official Italo Balbo during his transatlantic flight from Italy to the United States in 1933 visited with leaders of the Sioux tribe and accepted the Sioux's honorary bestowing of his incorporation into the Sioux with the Sioux position and name "Chief Flying Eagle".
