This unique collection presents texts in international relations from Ancient Greece to the first World War. Major writers such as Thucydides, Augustine, Aquinas, Machiavelli, Grotius, Kant and John Stuart Mill are represented by extracts of their key works; less well-known international theorists including John of Paris, Cornelius van Bynkershoek and Friedrich List are also included. Fifty writers are anthologized in what is the largest such collection currently available. The texts, most of which are substantial extracts, are organized into broadly chronological sections, each of which is headed by an introduction that places the work in its historical and philosophical context. Ideal for both students and scholars, the volume includes biographies and guides to further reading.
