This document discusses how trauma experienced by individuals can be transmitted across generations and negatively impact entire communities. It defines trauma and explores theories of its transgenerational transfer. Experiencing or being exposed to unresolved trauma is linked to increased rates of family violence, substance abuse, mental health issues, and criminal behavior in subsequent generations. Government policies are also discussed as exacerbating trauma and community dysfunction in Indigenous communities in Australia. The transmission of historical trauma through cultural and family systems helps explain the phenomenon of "dysfunctional community syndrome" seen in some Indigenous communities with high levels of compounded, unresolved trauma.
