Historical trauma is a relatively new yet crucial area of study within psychology, history, and related disciplines. This book introduces the concept of historical trauma by providing a comprehensive overview of the latest vocabulary, seminal psychological concepts, and quantitative research in the field. By drawing together cross-disciplinary threads and examining eight global contexts of historical trauma, the author highlights a wide-ranging and rigorous body of research that further adds to our clinical understanding of the possible long-term effects of collective trauma. The chapters also explore remedies against the historical effects of trauma, which tend to go far beyond psycho-therapeutic interventions, especially when they are dedicated to the culture of remembrance or empowerment for disadvantaged young people. By revealing a wealth of new ideas that point to a pivotal moment in the evolution of social sciences, this volume can help transform the way psychologists serve victimized communities around the world.
