Historical Context of United States
The United States has been a major country in the evolution of modern and contemporary art in the twentieth century, particularly in the post war period, when the cultural importance of New York asserted its influence over Paris, formerly considered as the most powerful art hub globally. Major art movements developed and fostered in extensive ways throughout the United States include Abstract Expressionism in diverse forms, Pop Art, including its West and East Coast variants, Minimalism, Conceptual Art, Neo-Expressionism, Graffiti and Street Art, plus various post-modern echoes of these many types. In the modern and contemporary age, the United States has exercised a powerful influence upon the international visual culture, due to the dominion 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.
