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, especially in the post war period, when the cultural status of New York asserted its influence over Paris, previously considered as the most powerful art centre globally. Leading art movements established and fostered in significant ways throughout the United States include Abstract Expressionism in varied forms, Pop Art, including its West and East Coast branches, Minimalism, Conceptual Art, Neo-Expressionism, Graffiti and Street Art, plus a multitude of post-modern iterations of these many types. In the modern and contemporary era, the United States has cultivated a powerful influence over the international visual culture, due to the hegemony of its economic and political systems. 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.
