This book proposes a theory of toleration wherein liberal democracies peacefully co-exist with non-democratic societies. It conceptualises international toleration in a way that is both faithful to the liberal tradition and at the same time explains why we should accept some nonliberal and non-democratic political communities as members in good standing in international society.

The volume delves into different theoretical understandings of the idea of toleration and what it has come to mean in today's highly polarised world. It argues that classifying states as liberal and nonliberal is important but cannot explain how they should relate to one another. Putting forward a new reconstruction of Rawls's theory of political liberalism, Maffettone makes a compelling case for the claim that the separation between domestic and international political domains can enable a liberal state to have equal respect and recognition for at least some nonliberal ones.

A major intervention in political and legal philosophy, this book will be indispensable to students and teachers of political theory, international relations, peace and conflict studies, international law, and human rights. It will also be of interest to government think tanks and civil servants.
