New technologies have opened up fresh possibilities for public diplomacy, but this has not erased the importance of history. On the contrary, the lessons of the past seem more relevant than ever, in an age in which communications play an unprecedented role. Blending history with insights from international relations, communication studies, psychology and contemporary practice, Cull explores the five core areas of public diplomacy: listening, advocacy, cultural diplomacy, exchanges, and international broadcasting. He also unpacks the approaches which have dominated in recent years - nation-branding and partnership - and sets out the foundations for successful global public engagement. The book is rich with case studies and examples drawn from ancient times through to our own digital age. This comprehensive and accessible introduction is essential reading for students, scholars and practitioners, as well as anyone interested in understanding or mobilizing global public opinion.
