This study examines the meteoric rise and subsequent disintegration of a vigorous American literary-political movement in the 1840s. Calling itself 'Young America', the group found a mouthpiece in the Democratic Review, a literary magazine funded by the Democratic Party and edited by the brash and charismatic John O'Sullivan. The Review was not only a major voice in American politics, but also sponsored such writers as Nathaniel Hawthorne and Walt Whitman and greatly inflenced Herman Melville, before it and Young America faded from the national consciousness after the Mexican-American War.
