Warfare was of central importance to ancient societies and recent years have seen an explosion of interest in almost every aspect of ancient warfare. This book, however, will fill an important gap, by providing a broad selection of source material with explanatory commentary covering the whole period of antiquity. What makes this book different is its focus on continuity and change through the long duration, the detailed commentaries on the evidence presented, as well as a holistic focus on war, society, economics and religion alongside tactical and strategic considerations. It will highlight problems and debates about ancient warfare, providing readers with the source material on key and controversial subjects, such as the origins and development of hoplite warfare or the introduction of the poor into the Roman Republican armies.
