Levá fronta [The Left Front] was an organization of Czech left-wing intellectuals. Founded in 1929, it replaced Devětsil – the Union of Modern Culture, with the aim to promote socialist culture and to organize collaboration of the progressive intelligence with the working class. Its founding members included Karel Teige, Stanislav Kostka Neumann, Bedřich Václavek, and Julius Fučík. Among later members of the organizations were Ivan Sekanina, Ladislav Štoll, Vladislav Vančura, the architects Karel Honzík, Jiří Kroha, Lubomír Linhart, Jiří Novotný, and many others.
The Left Front organized lectures, evening discussions and exhibitions. It also published the magazine Levá fronta (1930-1933) as well as leftist, especially political literature. The organization set up its branches in several towns, for example in Brno, and was divided into specialized sections (for architecture; economy; philosophy; medicine; literature; social science; and film and photography). The Left Front was eventually dissolved in 1938.
