This thesis studies France"s relations with the Little Entente during the term of Foreign Minister Delbos. It relies primarily on published diplomatic papers and memoirs. It discusses Delbos's background, the histories of Czechoslovakia, Yugoslavia, and Rumania from 1919-1936, and the formation of the Little Entente. The thesis focuses on France's efforts after the Rhineland crisis to strengthen her Eastern European alliances. Delbos chose the Little Entente over the Soviet Union as France's primary Eastern European alliance. Delbos's proposed Mutual Assistance Pact between France and the Little Entente and his Eastern European trip in December, 1937, failed owing to Yugoslavian and Rumanian opposition. German economic domination and intimidation of, and British disinterest in, Eastern Europe contributed to Yugoslavian and Rumanian rejection of France's overtures.
