In this book - the most comprehensive study of republican legal ideas to date - Professor Sellers traces the development of republican legal theory. Explaining the importance of popular sovereignty, the rule of law, the separation of powers and other essential republican legal characteristics, he argues that these republican institutions have introduced a new era of justice into politics.

Republican Principles in International Law considers the fundamental requirements of a just world order, as applied to public international law. This book sets the standard for legitimate government, both within and beyond the jurisdiction of separate states and nations.
