Describe how and why Abstract Expressionism transformed painting after 1945. At least (200-250 sentence)

Abstract expressionism was an American post–World War II art movement. Although the term abstract expressionism was first applied to American art in 1946 by the art critic Robert Coates, it had been used previously in Germany’s Der Sturm magazine in 1919.

Abstract expressionism is derived from the combination of the emotional intensity and self-denial of the German expressionists with the anti-figurative aesthetic of the European abstract schools, such as futurism, the Bauhaus, and synthetic cubism. Additionally, it has an image of being rebellious, anarchic, highly idiosyncratic, and nihilistic. In practice, the term is applied to any number of artists who worked (mostly) in New York during the 1940s.

Abstract expressionism has many stylistic similarities to the Russian artists of the early 20th century, such as Wassily Kandinsky. Although it is true that spontaneity or the impression of spontaneity characterized many of the abstract expressionists’ works, in reality most of these paintings involved careful planning, especially since their large size demanded it. In many instances, abstract art implied the expression of ideas that concern the spiritual, the unconscious, and the mind.
