INTRODUCTION

This enquiry is designed as a contribution to our understanding of how systems of states function. An understanding of how the contemporary society of states came to be what it is, and how it may develop in the future, requires a sense of how other societies operated and developed in the past. But we will not gain much understanding if we merely trace our present arrangements back in time. We need to examine the different patterns of relations between states in their own individuality and on their own merits; and then compare them.
