First published in 1917, Satow's Diplomatic Practice has long been hailed as a classic and authoritative text. An indispensable guide for anyone working in or studying the field of diplomacy, this seventh, centenary edition builds on the extensive revision in the sixth edition. The volume provides an enlarged and updated section on the history of diplomacy, including the exponential growth in multilateral diplomacy, and revises comprehensively the practice of diplomacy and the corpus of diplomatic and international law since the end of the Cold War. It traces the substantial expansion in numbers both of sovereign states and international and regional organisations and features detailed chapters on diplomatic privileges and immunities, diplomatic missions, and consular matters, treaty-making and conferences. The volume also examines alternative forms of diplomacy, from the work of NGOs to the use of secret envoys, as well as a study of the interaction with intelligence agencies and commercial security firms. It also discusses the impact of international terrorism and other violent non-state actors on the life and work of a diplomat. Finally, in recognition of the speed of changes in the field over the last ten years, this seventh edition examines the developments and challenges of modern diplomacy through new chapters on human rights and public/digital diplomacy by experts in their respective fields.
