Historical Context of United States
The United States has been a prominent country in the development 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 significant art hub worldwide. Major art movements developed and cultivated in significant 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 a multitude of post-modern echoes of these many types. In the modern and contemporary sphere, the United States has exercised a prevailing influence over the global visual culture, due to the dominion of its economic and political institutions. Key examples of critically acclaimed 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.
