Fortifications on the scale of these walls are unique in that they are (apart from individual castles) the only known military measure with long-term aims. The military aims sometimes proved of extremely long-term value, the most extreme example being the erection of the Great Wall of China. The aim of this volume is to find out the common denominator (if any) behind the creation of such fortifications, their effectiveness and their influence on a long and short-term basis. Contents include: The Limes * Hadrians Wall and the Antonine Wall * The "Danewerk" * The Frontera: Spanish Defences against the Moors * The Great Wall of China * The French Eastern Border * The Berlin Wall * The Jerusalem Wall

Research for and the writing of this book was funded by the award of a Leverhulme Trust Major Research Fellowship. The period c. AD300--1050, spanning the collapse of Roman rule to the coming of the Normans, was formative in the development of Wales. Life in Early Medieval Wales considers how people lived in late Roman and early medieval Wales, and how their lives and communities changed over the course of this period. It uses a multidisciplinary approach, focusing on the growing body of archaeological evidence set alongside the early medieval written sources together with place-names and personal names. It begins by analysing earlier research and the range of sources, the significance of the environment and climate change, and ways of calculating time. Discussion of the fourth, fifth, and sixth centuries focuses on the disintegration of the Roman market economy, fragmentation of power, and the emergence of new kingdoms and elites alongside evidence for changing identities, as well as important threads of continuity, notably Latin literacy, Christianity, and the continuation of small-scale farming communities. Early medieval Wales was an entirely rural society. Analysis of the settlement archaeology includes key sites such as hillforts, including Dinas Powys, the royal crannog at Llangorse, and the Viking Age and earlier estate centre at Llanbedrgoch alongside the development, from the seventh century onwards, of new farming and other rural settlements. Consideration is given to changes in the mixed farming economy reflecting climate deterioration and a need for food security, as well as craft working and the roles of exchange, display, and trade reflecting changing outside contacts. At the same time cemeteries and inscribed stones, stone sculpture and early church sites chart the course of conversion to Christianity, the rise of monasticism, and the increasing power of the Church. Finally, discussion of power and authority analyses emerging evidence for sites of assembly, the rise of Mercia, and increasing English infiltration, together with the significance of Offa's and Wat's Dykes, and the Viking impact. Throughout the evidence is placed within a wider context enabling comparison with other parts of Britain and Ireland and, where appropriate, with other parts of Europe to see broader trends, including the impacts of climate, economic, and religious change.

Migration, Mobility and Place in Ancient Italy challenges prevailing conceptions of a natural tie to the land and a demographically settled world. It argues that much human mobility in the last millennium BC was ongoing and cyclical. In particular, outside the military context 'the foreigner in our midst' was not regarded as a problem. Boundaries of status rather than of geopolitics were those difficult to cross. The book discusses the stories of individuals and migrant groups, traders, refugees, expulsions, the founding and demolition of sites, and the political processes that could both encourage and discourage the transfer of people from one place to another. In so doing it highlights moments of change in the concepts of mobility and the definitions of those on the move. By providing the long view from history, it exposes how fleeting are the conventions that take shape here and now.

Everyone has heard of the Great Wall of China and knows of Hadrian's Wall and the other barriers lining stretches of Rome's imperial frontiers. But Peter Spring's original new study demonstrates that far from being exceptional, the building of walls and other linear defences was commonplace among the peoples and states of pre-modern era. He finds examples virtually all across the globe and analyses their forms and strategic functions. He finds patterns for their distribution, an important recurrent theme being the divide between settled agriculture and nomads. The author argues that it is mistaken to view such undertakings as necessarily purely defensive measures that might be evidence of insecurity or a 'maginot line mentality', as they were in fact often about aggressive assertion of control over a region or strategic routes. This original and thought-provoking study brings new light and insight to a fascinating and neglected aspect of human political and military history. It The clear text is supported by numerous, specially drawn maps and photographs.
