Behdad shows how political, cultural, and legal texts have articulated American anxiety about immigration from the Federalist period to the present day. He reads texts both well-known—J. Hector St. John de Crèvecoeur’s Letters from an American Farmer, Alexis de Tocqueville’s Democracy in America, and Walt Whitman’s Leaves of Grass—and lesser-known—such as the writings of nineteenth-century nativists and of public health officials at Ellis Island. In the process, he highlights what is obscured by narratives and texts celebrating the United States as an open-armed haven for everyone: the country’s violent beginnings, including its conquest of Native Americans, brutal exploitation of enslaved Africans, and colonialist annexation of French and Mexican territories; a recurring and fierce strand of nativism; the need for a docile labor force; and the harsh discipline meted out to immigrant “aliens” today, particularly along the Mexican border.
