Book excerpt: This study chronicles U.S.-Habsburg relations from the early nineteenth century through the aftermath of World War I. By including both high-level diplomacy and analysis of diplomats' ceremonial and social activities, as well as an exploration of consular efforts to determine the citizenship status of thousands of individuals who migrated between the two countries, Nicole M. Phelps demonstrates the influence of the Habsburg government on the United States' integration into the nineteenth-century Great Power System and the influence of American racial politics on the Habsburg Empire's conceptions of nationalism and democracy.
