The art of the twentieth century is largely a reflection of political, social, economic changes, which took place very quickly. As such, art has rejected traditional prejudices and concepts, in an attempt to respond to a faster lifestyle and challenges of the twentieth century.

New perspectives, concepts, massive artistic productions, minimalism, have been created, as a way of fast and efficient artistic action and a reflection of reality.
