What is -- or makes a place -- a 'historic battlefield'? From one perspective the answer is simple -- it is a place where large numbers of people came together in an organised manner to fight one another at some point in the past. Yet from another perspective it is far more difficult to say. Why any such location is a place of battle rather than any other kind of event, and why it is especially historic, is hard to identify. This book sets out an answer to the question of what a historic battlefield is in the modern imagination, drawing upon examples from prehistory to the 20th century. Treating battles as events in the past and battlefields as places in the present, this book exposes the complexity of the concept of a historic battlefield and how it forms part of a Western understanding of the world. Taking its lead from new developments in battlefield study, especially archaeological approaches, it establishes a means by which these new approaches can contribute to a more radical thinking about war and conflict, especially to Critical Military and Critical Security studies. The book goes beyond the study of battles as separate and unique events to consider what they mean to us and why we need them to have particular characteristics. It will be of interest to archaeologists, historians, and students of modern war in all its forms.
