'As a collection, the volume is a valuable introduction to the spectrum of identities operating at the end of antiquity. As such it moves the discussion of group identity and community solidarity beyond the internal debates that have preoccupied Western medievalists and thus may provide a prolegomena for future comparative studies of community in the post-Roman world.' Speculum, Patrick J. Geary, Institute for Advanced Study 'The value of the book [...] does not so much lie in an abstract (and perhaps uncontroversial) point about identity as a dynamic development with consequences for the exercise of power. The real argument, and the real excitement here, feature in the riot of examples that move across northern and eastern Europe, the Mediterranean, the Caucasus, Ethiopia, the Arabian peninsula, Mesopotamia, the Iranian plateau, and even into the Eurasian steppe - and through this sweep of societies whose boundaries shifted and overlapped continuously, it becomes clear how deeply the question of community mattered to the politics of Late Antiquity and the early Middle Ages... Even a review this long reproduces the problem of identity in miniature: it highlights certain unifying features of the collection while bypassing almost all its subtle details. It is that subtlety which brings us much closer to the worlds of Late Antiquity and the early Middle Ages: for all the identities that were drawn in these centuries, they were so often porous and heterogeneous that one reaches a point where (as Haldon and Kennedy stress) the concept of "society" itself seems to reach its limits. One of the pleasures of this volume is that it maintains a productive tension throughout between these two views, between the bounded and the unlimited - both equally vital to understanding the period.' The Medieval Review '... this is a kaleidoscopic book with an ambitious scope... The present volume is for those who seek varieties of approaches and perspectives through which they are bound to find complex visions of community past as well as present.' Bryn Mawr Classical Review
