Book excerpt: This book examines the possibility and role of a Cahokian diaspora to understand cultural influence, complexity, historicity, and movements in the Mississippian Southeast. Collectively the chapters trace how the movements of Cahokian and American Bottom materials, substances, persons, and non-human bodies converged in the creation of Cahokian identities both within and outside of the Cahokia homeland through archaeological case studies that demonstrate the ways in which population movements foment social change. Drawing initial inspiration from theories of diaspora, the book explores the dynamic movements of human populations by critically engaging with the ways people materially construct or deconstruct their social identities in relation to others within the context of physical movement. This book is of interest to students and researchers of archaeology, anthropology, sociology of migration and diaspora studies.
