Frontiers and territorial borders are places of contested power where societies collide, interact, and interconnect. Using bioanthropological case studies from around the world, this volume explores how people in the past created, maintained, or changed their identities while living on the edge between two or more different spheres of influence. Essays in this volume examine borderland settings in cultural contexts that include Roman Egypt, Iron Age Italy, eleventh-century Iceland, and the precontact American Great Basin and Southwest. Contributors look at isotope data, skeletal stress markers, craniometric and dental metric information, mortuary arrangements, and other evidence to examine how frontier life can affect health and socioeconomic status. Illustrating the many meanings and definitions of frontiers and borderlands, they question assumptions about the relationships between people, place, and identity. As national borders continue to ignite controversy in today's society and politics, the research presented here is more important than ever. The long history of people who have lived in borderland areas helps us understand the challenges of adapting to these dynamic and often violent places.
