American theatres stratified in the Jacksonian Era, and the Bowery emerged as the home of American nativists and populist causes, placing it in direct contrast to the Park Theatre's cultivated image of traditional European high culture. This was partially the result of an anti-British theatre riot at the Park; Hamblin renamed the playhouse "the American Theatre, Bowery" in reaction. Hamblin hired unknown American actors and playwrights and allowed them to play for long runs of up to a month. Before 1843, early blackface performers such as George Washington Dixon and Thomas D. Rice played there frequently, and acts such as J. B. Booth, Edwin Forrest, Louisa Lane Drew, and Frank Chanfrau also gained renown on the Bowery's stage. George L. Fox and his pantomime became the most popular act at the Bowery until after the Civil War. Bowery productions also debuted or popularized a number of new character types, including the Bowery B'hoy, the Yankee, the Frontiersman, and the blackface Negro.
