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 asserted its influence over Paris, previously thought of as the most significant art hub internationally. Major art movements developed and cultivated in important ways throughout the United States include Abstract Expressionism in varied forms, Pop Art, including its West and East Coast variants, Minimalism, Conceptual Art, Neo-Expressionism, Graffiti and Street Art, plus a multitude of post-modern echoes of these many movements. In the modern and contemporary period, the United States has cultivated a prevailing influence upon the global visual culture, due to the hegemony of its economic and political systems. Key examples of important U.S artists of the modern and contemporary era 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.
