The document discusses how Henry Wadsworth Longfellow incorporated specific references to the American landscape in his epic poem The Song of Hiawatha in order to create a sense of national identity and culture. Longfellow deliberately altered original Native American legends by adding descriptions of locations, plants, animals, and terrain that would have been familiar to American readers. This was likely an attempt to establish a uniquely American literary tradition distinct from British romanticism, as well as to foster a common bond between Americans through their shared natural environment during a period of social and political tensions.
