In 1716, the French diplomat and author Francois de Calli res published the treatise "De la Maniere de negocier avec les souverainsoan outstandingly successful manual of advice for diplomats, perhaps the best of its kind ever written. It has become the classic text, highly regarded by 18th century statesmen, who considered it essential reading for prospective diplomats, and by modern historians who have praised its insights into the conventions and techniques that remained a distinctive feature of European statecraft for almost 300 years. This book is the first, complete critical edition of Callieres' work based on an accurate but virtually unknown English translation of 1716. It also includes a biographical introduction, based on French manuscript sources, which provides an account of Callieres' life as writer and diplomat, a discussion of the origin of the work and an assessment of the intellectual and historical background to which the treatise belongs. In addition, the book includes appendixes on the French political academy, Callieres' library and a list of his publications as well as those of his father, Jacques, also a notable author in his day. The volume concludes with a bibliography of works on diplomatic theory covering the period 1648 to 1815. This reprint of the 1983 edition by Leicester University Press makes available once again this historical work of enduring value.
