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, particularly in the post war era, when the cultural prominence of New York assumed primacy over Paris, previously considered as the most powerful art centre internationally. Leading art movements developed and cultivated in important ways throughout the United States include Abstract Expressionism in varied forms, Pop Art, including its West and East Coast variants, Minimalism, Conceptual Art, Neo-Expressionism, Graffiti and Street Art, plus various post-modern repetitions of these many movements. In the modern and contemporary period, the United States has cultivated a prevailing influence upon the worldwide visual culture, due to the dominion of its economic and political structures. Key examples of world renowned 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.
