Osvobozené divadlo (1926–1938) (Liberated Theatre or Prague Free Theatre) was a Prague avant-garde theatre scene founded as the theatre section of an association of Czech avant-garde artists Devětsil (Butterbur) in 1926. The theatre's beginnings were strongly influenced by Dadaism and Futurism, later by Poetism (a specific Czech art movement). The theatre was very leftist oriented, but it could also be critical of the Communists. One of the founders, Jiří Frejka, came up with the name in 1926. In the theatre both authorial plays and works by well-established modern authors; such as G. Apollinaire, A. Jarry, J. Cocteau, A. Breton, F. T. Marinetti, and V. Nezval were performed. The modern conception of the scene also laid more emphasis on lighting and the theatrical conception adjured more cooperation and contacts between actors and audience.
