The Blok movement consisted of a Constructivist group created in 1924 that spoke against the decorative and nationalist preoccupations of the Cracow School. The group's concerns were first iterated by Mieczyslaw Szczuka and Teresa Zarnowerówna in their magazine Blok. These thinkers closely affiliated with Russian Vladimir Tatlin in their emphasis on technology and utilitarianism rather than on aesthetics.
Ultimately however their emphasis on Functionalism rather than on ¨pure art¨ led to the groups´ dissolve in 1926. Many of Blok members soon associated with Praesens, a Polish Modernist pressure group formed in the same year.
