During the Nazi rise to power in the 1930s many artists fled Europe to the United States. By the early 1940s the main movements in modern art, expressionism, cubism, abstraction, surrealism, and dada were represented in New York: Marcel Duchamp, Fernand Léger, Piet Mondrian, Jacques Lipchitz, André Masson, Max Ernst, André Breton, were just a few of the exiled Europeans who arrived in New York. The rich cultural influences brought by the European artists were distilled and built upon by local New York painters. The climate of freedom in New York allowed all of these influences to flourish. The art galleries that primarily had focused on European art began to notice the local art community and the work of younger American artists who had begun to mature. Certain artists at this time became distinctly abstract in their mature work. During this period Piet Mondrian's painting "Composition No. 10", 1939–1942, characterized by primary colors, white ground and black grid lines clearly defined his radical but classical approach to the rectangle and abstract art in general.
