Abstract art developed in the late 19th century as artists felt a need for a new art form that reflected the fundamental changes in technology, science, and philosophy. It uses forms, colors, and lines instead of attempting to represent recognizable reality. In the 20th century, several movements contributed to abstract art becoming more removed from visual references, including Romanticism, Impressionism, and Expressionism. Artists like Kandinsky and Mondrian were also influenced by Eastern and occult philosophies. During this time, abstract art developed in Russia, Germany, France, and the United States. It became an international art movement as artists fled Europe during World War II and spread abstract styles around the world.
