This book is about political orders, historical ones, the current one but also future alternative ones. An understanding of how the contemporary world order came to be what it is and how it may develop in the future, is an exploration of the expansion of the international society of European states across the rest of the globe, its transformation from a society fashioned in Europe and dominated by Europeans into the global international society of today, with its nearly two hundred states, the great majority of which are not European. Such an understanding requires a sense of how other societies operated and developed in the past. In fact, our present international society is puzzling if looked at in isolation.

Of particular interest in the book is the (changing) view on the use of force as a legal/legitimate means in the conduct of international politics. Briefly put: what does the seemingly new attitude towards the use of force as an acceptable means in international relations that we are witnessing today imply for the future world order?
