Historical Context of United States
The United States has been a prominent country in the evolution of modern and contemporary art in the twentieth century, especially in the post war period, when the cultural prominence of New York asserted its influence over Paris, previously considered as the most important art hub worldwide. Major art movements established and fostered in important ways throughout the United States include Abstract Expressionism in various forms, Pop Art, including its West and East Coast variants, Minimalism, Conceptual Art, Neo-Expressionism, Graffiti and Street Art, plus various post-modern iterations of these many types. In the modern and contemporary era, the United States has exercised a powerful influence over the worldwide visual culture, due to the authority of its economic and political structures. Key examples of critically acclaimed 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.
