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, especially in the post war era, when the cultural prominence of New York asserted its influence over Paris, formerly considered as the most significant art hub in the world. Major art movements established and cultivated in important 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 era, the United States has exercised a prevailing influence over the visual culture of the World, due to the authority of its economic and political systems. Key examples of important 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.
