American modernism is a cultural movement that emerged in the early 20th century, characterized by a break from traditional forms of art, literature, and architecture. It sought to capture the complexities of modern life, often reflecting themes of alienation, fragmentation, and innovation. Key figures include writers like F. Scott Fitzgerald and Ernest Hemingway, as well as artists such as Georgia O'Keeffe and Edward Hopper. This movement was influenced by significant historical events, including World War I and the rise of industrialization. American modernists experimented with new techniques and styles, embracing abstraction and exploring the subconscious. Their work laid the foundation for many contemporary artistic expressions.
