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.

The most famous example of fortification in the world, the Great Wall of China stretches for more than 6,000km across inhospitable terrain. Charting its development from its earliest origins in the 7th century BC through to the present day, this account reveals the true history of the wall, and explores the myths that surround it. Included are details of what it was like to live within the wall, how it was garrisoned and patrolled, and a discussion of how effective it was against attack. Through extensive examination of both ancient and modern sources, colour maps, artwork and photographs, this book illustrates why the wall is one of the great wonders of the world.

Which ancient army boasted the largest fortifications, and how did the competitive build-up of military capabilities shape world history? Few realise that imperial Rome had a serious competitor in Late Antiquity. Late Roman legionary bases, normally no larger than 5ha, were dwarfed by Sasanian fortresses, often covering 40ha, sometimes even 125-175ha. The latter did not necessarily house permanent garrisons but sheltered large armies temporarily – perhaps numbering 10-50,000 men each. Even Roman camps and fortresses of the Early and High Empire did not reach the dimensions of their later Persian counterparts. The longest fort-lined wall of the late antique world was also Persian. Persia built up, between the fourth and sixth centuries AD, the most massive military infrastructure of any ancient or medieval Near Eastern empire – if not the ancient and medieval world. Much of the known defensive network was directed against Persia’s powerful neighbours in the north rather than the west. This may reflect differences in archaeological visibility more than troop numbers. Urban garrisons in the Romano-Persian frontier zone are much harder to identify than vast geometric compounds in marginal northern lands. Recent excavations in Iran have enabled us to precision-date two of the largest fortresses of Southwest Asia, both larger than any in the Roman world. Excavations in a Gorgan Wall fort have shed much new light on frontier life, and we have unearthed a massive bridge nearby. A sonar survey has traced the terminal of the Tammisheh Wall, now submerged under the waters of the Caspian Sea. Further work has focused on a vast city and settlements in the hinterland. Persia’s Imperial Power, our previous project, had already shed much light on the Great Wall of Gorgan, but it was our recent fieldwork that has thrown the sheer magnitude of Sasanian military infrastructure into sharp relief.

“A lively popular history of an oft-overlooked element in the development of human society” (Library Journal)—walls—and a haunting and eye-opening saga that reveals a startling link between what we build and how we live. With esteemed historian David Frye as our raconteur-guide in Walls, which Publishers Weekly praises as “informative, relevant, and thought-provoking,” we journey back to a time before barriers of brick and stone even existed—to an era in which nomadic tribes vied for scarce resources, and each man was bred to a life of struggle. Ultimately, those same men would create edifices of mud, brick, and stone, and with them effectively divide humanity: on one side were those the walls protected; on the other, those the walls kept out. The stars of this narrative are the walls themselves—rising up in places as ancient and exotic as Mesopotamia, Babylon, Greece, China, Rome, Mongolia, Afghanistan, the lower Mississippi, and even Central America. As we journey across time and place, we discover a hidden, thousand-mile-long wall in Asia's steppes; learn of bizarre Spartan rituals; watch Mongol chieftains lead their miles-long hordes; witness the epic siege of Constantinople; chill at the fate of French explorers; marvel at the folly of the Maginot Line; tense at the gathering crisis in Cold War Berlin; gape at Hollywood’s gated royalty; and contemplate the wall mania of our own era. Hailed by Kirkus Reviews as “provocative, well-written, and—with walls rising everywhere on the planet—timely,” Walls gradually reveals the startling ways that barriers have affected our psyches. The questions this book summons are both intriguing and profound: Did walls make civilization possible? And can we live without them? Find out in this masterpiece of historical recovery and preeminent storytelling.

Walls are being built at a dizzying pace to separate us, cocoon us, and exclude us. The contributors to this volume illuminate the roles and uses of walls around the world—in contexts ranging from historic neighborhoods to contemporary national borders. They argue that more and more walls are being built even though they are a paradox in a neoliberal world in which people, goods, and ideas are supposed to move freely. The walls examined in this volume do not share a common form or type, but they do share a common political purpose: they determine and defend racist definitions of social belonging by controlling access and movement. The contributors include archaeologists, anthropologists, geographers, and sociologists. They bring different perspectives and insights to the scale, form, and impact of this phenomenon of “walling in” and “walling out.”
