The document provides an overview of developments in art during the 1920s, including the emergence of Dada and Surrealist movements. Dadaists like Hannah Hoch used photomontage to critique post-WWI German society. The Bauhaus school was also founded during this time with the goal of uniting art and industry. In 1924, Andre Breton published the first Surrealist manifesto, advocating the exploration of unconscious thought and dream imagery. Surrealist techniques like automatism and found objects aimed to access the subconscious mind.
