Dadaism’s anti-war attitude, rejection of established aesthetic norms, and embracing of randomness, absurdity, and humor typified the movement. Dadaists attempted to question the prevailing political and cultural institutions of their day by subverting established conventions of society and art. They explored new modes of expression, such as photomontage, collage, and Dada poetry, and created works that were usually purposefully provocative and offensive.
