The United States or by American artists. Before colonization there were many flourishing traditions of Native American art, and where the Spanish colonized Spanish Colonial architecture and the accompanying styles in other media were quickly in place. Early colonial art on the East Coast initially relied on artists from Europe, artists primarily painted portraits, and some landscapes in a style based mainly on English painting. Furniture-makers imitating English styles and similar craftsmen were also established in the major cities, but in the English colonies, locally made pottery remained resolutely utilitarian until the 19th century, with fancy products imported.
After World War II, New York replaced Paris as the center of the art world. Since then many American movements have shaped Modern and Postmodern art. Art in the United States today covers a huge range of styles.
