The Practice of Diplomacy

De la manière de négocier avec les souverains, commonly known as The Practice of Diplomacy, is a seminal work by French diplomat François de Callières published in 1716. This book is considered a foundational text on diplomacy, outlining the essential qualities, responsibilities, conduct, and strategies for an ideal negotiator.1

Callières' treatise emphasizes the importance of building trust and advocates for the judicious use of flattery and bribery, while cautioning against deceit as detrimental to an envoy's credibility. The work reflects the evolving nature of diplomacy in the 18th century, where professionalization and a focus on national interest (raison d'état) were becoming increasingly prominent.12
