American Expressionism is an art movement that emerged in the early 20th century, primarily during the 1920s and 1930s. It focuses on conveying emotional experiences rather than depicting reality. Artists used bold colors, exaggerated forms, and dynamic compositions to express feelings and ideas, often reflecting the social and political issues of their time. Key figures in American Expressionism include artists like Edward Hopper and Jackson Pollock. This movement is characterized by its emphasis on individual perspective and subjective interpretation, making it a significant part of the broader Expressionism movement that originated in Europe.
