Conventional wisdom would have us believe that every immigrant to the United States "became American," by choice and with deliberate speed. Yet, as Special Sorrows shows us, this is simply untrue. In this compelling revisionist study, Matthew Frye Jacobson reveals tenacious attachments to the Old World and explores the significance of homeland politics for Irish, Polish, and Jewish immigrants at the turn of the twentieth century. Drawing on Yiddish, Polish, and English-language sources, Jacobson discovers the influence of nationalist ideologies in the overt political agendas of such ethnic associations as the Knights of Zion and the Polish Falcons, as well as in newspapers, vernacular theater, popular religion, poetry, fiction, and festivals both religious and secular. In immigrant communities, he finds that nationalism was a powerful component of popular sensibility. A captivating example of Jacobson's thesis is immigrant reaction to American intervention in Cuba. Masculinist/militarist strains of nationalist culture met with the keen impulse to aid a subjugated people. The three national groups, laden with memories of their own subjugation, found an unlikely outlet in the Caribbean.
