Little Entente, a political and military alliance of Czechoslovakia, Yugoslavia, and Romania. These countries had profited from the dissolution of Austria-Hungary after World War I, and they had a common interest in preventing any restoration of the old regime. At the suggestion of Eduard BeneŇ° of Czechoslovakia, three agreements were made (Czechoslovakia-Yugoslavia, 1920; Romania-Yugoslavia, 1921; Czechoslovakia-Romania, 1921) encouraging economic cooperation. France backed the Little Entente by its alliance with Czechoslovakia. The Little Entente declined after Nazi Germany began to rearm in 1933. The alliance was destroyed in 1938 when the Munich Pact delivered the Sudetenland, a part of Czechoslovakia, to Germany.
