American literary nationalism
American literary nationalism was a literary movement in the United States in the early-to mid 19th century, which consisted of American authors working towards the development of a distinct American literature. Literary figures such as Henry Wadsworth Longfellow, William Cullen Bryant and William Ellery Channing advocated the creation of a definitively American form of literature with emphasis "on spiritual values and social usefulness." Longfellow wrote that "when we say that the literature of a country is national, we mean that it bears upon it the stamp of national character." Many authors of the time also advocated tying the literature to religion.
