During the Second Polish Republic, Nijinska headed the Balet Polski, aka Les Ballets Polonais, aka The Polish Ballets newly formed in Warsaw in 1937. This company was the brainchild of poet Jan Lechoń, and created with the assistance of M. Waclaw Jedrzejewicz, Minister of Public Education and President of the Organization Committee of the Polish Section to the Art and Technical Exhibition in Paris. The company's general director was Arnold Szyfman. For the first season, 1937-1938, Nijinska created five new ballets including "Baśń krakowska" ("La Légende de Cracovie)," to music by Michal Kondracki; "Pieśń o ziemi naszej" ("Le Chant de la Terre)," to music by Roman Palester; "Koncert E-moll Chopina (Concerto de Chopin)," to Frédéric Chopin's B-minor piano concerto; "Apollo i dziewczyna" ("Apollon et la Belle)," to music by Ludomir Rozycki; and "Wezwanie (Le Rappel)," set to a score by Boleslaw Woytowicz. This repertoire featured scenery and costumes designed by Teresa Roszkowska, Waclaw Borowski, Wladyslaw Daszewski, and Irena Lorentowicz-Karwowska. The souvenir program for this company's Covent Garden appearances states: "Every gesture and every colour, the ebb and flow of the groups, each step of the soloists, the spirit and harmony of the Polish Ballets are imbued with the artistic ideals of Bronislava Nijinska and her ardent desire that the world should see the dances of her country in their noblest and most beautiful form." At the Paris Exposition Internationale of that year, this Polish Ballet won the Grand Prix for performance, Nijinska the Gran Prix for choreography. In 1938 the Ballets Polonais was directed by Leon Wójcikowski. It appeared at the New York World's Fair in 1939, but World War II caused its closure.
