Postmodern art emerged in the 20th century in response to modernism. It rejects the fixed views and purity of form in modern art in favor of a more complex and uncertain view of the world. Postmodernism aims to eliminate boundaries between high and popular culture. Some key movements in postmodern art include minimalism, post-minimalism, new classicism, conceptual art, installation art, and lowbrow art. Postmodern works are characterized by their subjective nature, interest in social issues, and eclectic styles and mediums.
