"The book builds an extraordinarily careful argument about the specificities of context in the 1850s and 60s necessary to an understanding of how terrorism as a distinctive body of political thinking and practice arrived in the modern world, focusing on the field of understanding that coalesced around "freedom, nation and violence" in the epoch framed by the French Revolution and Revolutions of 1848. It does not fall into common trap of the available literatures, viz. to approach the 'genealogies' from an excessively presentist point of view. Instead, Dietze approaches the 1850s and 60s as a generative crucible for the conjunction of ideas and influences that need to be very carefully historicized as such if we're to have any chance of understanding the subsequent intellectual and political histories concerned. In its willingness to engage explicitly and at length with the literatures in political science as well as the writing theoretically about terrorism in general, Dietze's book has unusual strength for a historian."The book is impressively "transnational" in the terms that have become aspiringly normative for so many theoretically self-aware and ambitious historians during the past decade.""Dietze brilliantly makes these familiar and well-established histories and perceptions strange.""Another vital and original aspect of the study is its emphasis on media history and the particular characteristics of the mid 19th century public sphere -- BOTH in terms of the circulatory conditions needed for the transnational quality of the history she's trying to reconstruct AND for the key argument she's making about impact and reception. In other words, this is partly an argument about mechanics and the particular means of transmission and circulation. But it's also about the ontological grounds of political thought and political agency created out of this remarkable transnational circuitry."
