The poetry of the United States naturally arose first during its beginnings as the Constitutionally-unified thirteen colonies (although prior to this, a strong oral tradition often likened to poetry existed among Native American societies). Unsurprisingly, most of the early colonists' work relied on contemporary British models of poetic form, diction, and theme. However, in the 19th century, a distinctive American idiom began to emerge. By the later part of that century, when Walt Whitman was winning an enthusiastic audience abroad, poets from the United States had begun to take their place at the forefront of the English-language avant-garde.
This position was sustained into the 20th century to the extent that Ezra Pound and T.S. Eliot were perhaps the most influential English-language poets in the period during World War I. By the 1960s, the young poets of the British Poetry Revival looked to their American contemporaries and predecessors as models for the kind of poetry they wanted to write. Toward the end of the millennium, consideration of American poetry had diversified, as scholars placed an increased emphasis on poetry by women, African Americans, Hispanics, Chicanos and other subcultural groupings. Poetry, and creative writing in general, also tended to become more professionalized with the growth of creative writing programs in the English studies departments of campuses across the country.
