Ultraism, also known as ultra-modernism, is a literary and artistic movement in Spain and Latin America that was popularized in the early 1920s. The movement is characterized by the use of unconventional techniques and themes, and often rejects traditional literary and cultural norms. Synonyms for ultraism include avant-garde, experimentalism, radicalism, and futurism. These synonyms suggest a desire to break away from traditional forms of expression and embrace the new, the innovative, and the futuristic. They also imply a willingness to take risks and push boundaries, which are essential qualities of the ultraist movement.
