Sovereignty, Rights and Justice surveys the relationship between international relations theory and political theory, showing the way in which these two discourses, once considered separate, are now intertwined. In the first part of the book an historical overview of the international political theory on the 'Westphalia System' is presented, with brief accounts of the law of nations, and the notion of an 'international society' as well as an examination of the international thought of the Enlightenment and of nineteenth- century industrial society.
