Historical Context of United States
The United States has been a major country in the development 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 important art hub in the world. Leading art movements established and cultivated in extensive ways throughout the United States include Abstract Expressionism in various forms, Pop Art, including its West and East Coast variants, Minimalism, Conceptual Art, Neo-Expressionism, Graffiti and Street Art, plus various post-modern iterations of these many types. In the modern and contemporary sphere, the United States has exercised a strong influence upon the visual culture of the World, due to the authority of its economic and political systems. 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.
