Informalism or Art Informel is a pictorial movement from the 1943–1950s, that includes all the abstract and gestural tendencies that developed in France and the rest of Europe during the World War II, similar to American abstract expressionism started 1946. Several distinguishing trends are identified within the movement such as lyrical abstraction, matter painting, New Paris School, tachisme and art brut. The French art critic Michel Tapié coined the term "art autre" in the homonymous book published in 1952 in relation to non-geometric abstract art. It was instrumental in improving the concept of abstract art in France during the Early 1950s. Its use in the expression of political ideologies in South America during the Early 1950s was quite common, as it was seen as the main way to show support for the changing political climate.
