But it remains controversial in world politics and conceptually contested among scholars. This book examines the principle in relation to the exercise of state power in domestic jurisdictions and international affairs.One of the most important developments in world politics in the last decade has been the spread of the idea that state sovereignty comes with responsibilities as well as privileges, and that there exists a global responsibility to protect people threatened by mass atrocities. The principle of the Responsibility to Protect is an acknowledgment by all who live in zones of safety of a duty of care towards those in zones of danger. Thakur and Maley argue that this principle has not been discussed sufficiently in the context of international and political theory, in particular the nature and foundations of political and international order and the strength and legitimacy of the state. The book brings together a range of authors to discuss the different ways in which the Responsibility to Protect can be theorised, using case studies to locate the idea within wider traditions of moral responsibilities in international relations.Part I.
