Historical Context of United States
The United States has been a major country in the development of modern and contemporary art in the twentieth century, particularly in the post war era, when the cultural importance of New York assumed primacy over Paris, previously thought of as the most important art hub globally. Leading art movements established and cultivated in extensive ways throughout the United States include Abstract Expressionism in diverse forms, Pop Art, including its West and East Coast variations, Minimalism, Conceptual Art, Neo-Expressionism, Graffiti and Street Art, plus a multitude of post-modern iterations of these many types. In the modern and contemporary era, the United States has exercised a prevailing influence upon the worldwide visual culture, due to the dominion of its economic and political institutions. Key examples of world renowned U.S artists of the modern and contemporary period include Jackson Pollock, Mark Rothko, Jasper Johns, Robert Rauschenberg, Cy Twombly, Andy Warhol, Roy Lichtenstein, Frank Stella, Donald Judd, Cindy Sherman, Barbara Kruger, Julian Schnabel, Jean-Michel Basquiat and Keith Haring.
