This chapter summarises the main themes of the book, placing individual chapters within diverse thematic frameworks. After a brief discussion of the evolution of human violence, it introduces the Palaeolithic and Neolithic beginnings of human violence before examining prehistoric and ancient warfare. This includes considerations of the role of farming in the Neolithic, the more specialised warfare of the Bronze and Iron Ages, the era of classical antiquity and the growing importance of osteoarchaeology in understanding early violence. The discussion then continues with the other themes of the volume: intimate and collective violence; religion, ritual and violence; violence, crime and the state; and representations and constructions of violence.
