Returning World War II veterans created a post-war economic boom and the development of large housing tracts in eastern Queens. New York emerged from the war unscathed as the leading city of the world, with Wall Street leading America's place as the world's dominant economic power. The United Nations Headquarters was completed in 1952, solidifying New York's global geopolitical influence, and the rise of abstract expressionism in the city precipitated New York's displacement of Paris as the center of the art world.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What artistic movement caused New York to overtake Paris as the global art center?
abstract expressionism
