What influenced Abstract art?
During the late 19th Century there were various artistic movements which embraced non-naturalistic colors, distorted figures and/or minimalist representations of reality and real-world objects. (Impressionism and Expressionism). In the early 20th Century, Picasso and Braque began experimenting with a further distortion of reality (Cubism). Although Cubist works are abstracted, they are not considered abstract art because they are all tied to representation of real world objects. The first entirely abstract works of art (those free of representation) were the works of Kandinsky, Mondrian and Malevich. All three artists were influenced by the aforementioned artistic movements.
