A public health approach to human trafficking requires a nuanced understanding of its root causes. This textbook applies a historical lens to human trafficking from expert resources for the multidisciplinary public health learner and worker. The book challenges the anti-trafficking paradigm to meaningfully understand historical legacies of present-day root-causes of human trafficking. This textbook focuses on history's utility in public health. It describes history to contextualize and explain present times, and provides public health lessons in trafficking prevention and intervention. Public health recognizes the importance of multiple systems to solve big problems, so the chapters illustrate how current anti-trafficking efforts in markets and public systems connect with historical policies and data in the United States. Topics explored include: Capitalism, Colonialism, and Imperialism: Roots for Present-Day Trafficking Invisibility, Forced Labor, and Domestic Work Addressing Modern Slavery in Global Supply Chains: The Role of Businesses Immigration, Precarity, and Human Trafficking: Histories and Legacies of Asian American Racial Exclusion in the United States Systemic and Structural Roots of Child Sex Trafficking: The Role of Gender, Race, and Sexual Orientation in Disproportionate Victimization The Complexities of Complex Trauma: An Historical and Contemporary Review of Healing in the Aftermath of Commercialized Violence Historical Context Matters: Health Research, Health Care, and Bodies of Color in the United States Understanding linkages between contemporary manifestations of human trafficking with their respective historical roots offers meaningful insights into the roles of public policies, institutions, cultural beliefs, and socioeconomic norms in commercialized violence. The textbook identifies sustainable solutions to prevent human trafficking and improve the health of the Nation. The Historical Roots of Human Trafficking is essential reading for students of public health, health sciences, criminology, and social sciences; public health professionals; academics; anti-trafficking advocates, policy-makers, taskforces, funders, and organizations; legislators; and governmental agencies and administrators.
