On what grounds do we speak of 'the avant-garde' in inter­war European culture? Why do we understand the conflicts and quarrels among these diverse movements as expressing a shared attitude - the culture of the manifesto, the drive to reject, to explore, to renew - that trumps the conflicts and quarrels themselves? Why do the stern rationalism of a functionalist building and the irreverent irrationalism of a Dadaist performance seem heralds of a similar spirit?The Czech avant-garde theorist Karel Teige (1900-1951) regarded architecture and film as providing the key to formulating a unified theory that would capture this 'integrity of the avant-garde'. Teige - whose thought has many points of contact with celebrated figures such as Georg Lukács and Walter Benjamin, and who was a close associate of Le Corbusier, André Breton, and Hannes Meyer - reveals how a vibrant 'alternative' avant-garde tradition can raise central questions for understanding European modernism more broadly.
