This book is a comprehensive overview of the theory, history, law, institutional framework and culture of global diplomacy. It reflects on the key existential challenges to the institution and addresses aspects that are often overlooked in diplomatic studies: inter alia diplomatic law, development-driven diplomacy and the bureaucracy of diplomatic practice. All chapters are extensively illustrated with recent case examples from across the world. Special emphasis is placed on incorporating perspectives from Africa and other developing regions in the Global South, so as to balance the Eurocentrism of traditional diplomatic literature.
