This book examines the lasting impact of war on individuals and their communities in pre-modern Europe. Research on combat stress in the modern era regularly draws upon the past for inspiration and validation, but to date no single volume has effectively scrutinised the universal nature of combat stress and its associated modern diagnoses. Highlighting the methodological obstacles of using modern medical and psychological models to understand pre-modern experiences, this book challenges existing studies and presents innovative new directions for future research. With cutting-edge contributions from experts in history, classics and medical humanities, the collection has a broad chronological focus, covering periods from Archaic Greece (c. sixth and early fifth century BCE) to the British Civil Wars (seventeenth century CE). Topics range from the methodological, such as the dangers of retrospective diagnosis and the applicability of Moral Injury to the past, to the conventionally historical, examining how combat stress and post-traumatic stress disorder may or may not have manifested in different time periods. With chapters focusing on combatants, women, children and the collective trauma of their communities, this collection will be of great interest to those researching the history of mental health in the pre-modern period.
