Abstract: This book explores modern international society by drawing on the closely related disciplines diplomatic and military history, international legal studies, and international political theory. It analyses the most significant international issues to date, including peace and security, war and intervention, human rights, failed states, territories and boundaries, and democracy. It then considers the future of international society in the 21st century, and argues that the pluralist relationship of sovereign states is one that upholds freedom and respects human diversity.

Keywords: international society, peace, security, war, intervention, failed states, democracy, sovereignty
