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, especially in the post war era, when the cultural prominence of New York asserted its influence over Paris, formerly thought of as the most important art centre in the world. 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 branches, Minimalism, Conceptual Art, Neo-Expressionism, Graffiti and Street Art, plus various post-modern repetitions of these many movements. In the modern and contemporary age, the United States has cultivated a powerful influence over the worldwide visual culture, due to the authority of its economic and political structures. 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.
