Abstractionism developed in the early 1920s following World War 1 and the Russian Revolution. Artists like Kandinsky, Malevich, and Mondrian created non-objective works using geometric shapes and colors without depicting real-world objects. They believed this approach revealed deeper spiritual meanings and could communicate universal ideas. Kandinsky saw color and shape as symbolic and thought works should be felt, not just observed. Malevich's suprematism used basic forms to overcome conflicts between man and nature. Mondrian simplified shapes toward clarity and universal harmony. Their innovations influenced visual arts and design.
