Rowdy Carousals makes important interventions in nineteenth-century theatre history with regard to the Bowery Boy, a raucous, white, urban character most famously exemplified by Mose from A Glance at New York in 1848. The book's examination of working-class whiteness on stage, in the theatre, and in print culture invites theatre historians and critics to check the impulse to downplay or ignore questions about race and ethnicity in discussion of the Bowery Boy and further explores links between the Bowery Boy's rowdyism in the nineteenth century and the resurgence of white supremacy in the early twenty-first century.
