Do the Romans have anything to teach us about the way that they saw the world, and the way they ran their empire? How did they deal with questions of frontiers and migration, so often in the news today? This collection of ten important essays by C. R. Whittaker, engages with debates and controversies about the Roman frontiers and the concept of empire. Truly global in its focus, the book examines the social, political and cultural implications of the Roman frontiers in Africa, India, Britain, Europe, Asia and the Far East, and provides a comprehensive account of their significance.
