In The Representation of External Threats, Eberhard Crailsheim and María Dolores Elizalde present a collection of articles that trace the phenomenon of external threats in a multitude of settings across Asia, America, and Europe. The scope ranges from military threats against the Byzantine rulers of the 7th century to the perception of cultural and economic threats in the late 19th century Atlantic, and includes conceptual threats to the construction of national histories. Focussing on the different ways in which such threats were socially constructed, the articles offer a variety of perspectives and interdisciplinary methods to understand the development and representations of external threats, concentrating on the effect of 'threat communication' for societies and political actors.
