Definition
Historical trauma is the cumulative emotional and psychological wounding of communities across generations resulting from massive group trauma — colonization, slavery, genocide, forced displacement.
Why it matters
Historical trauma is real, documentable, and consequential for present-day health.
The Science
Yellow Horse Brave Heart, Duran, and others have developed frameworks in Indigenous contexts. Epigenetic and social mechanisms are proposed. Present-day health disparities partly reflect these histories.
The NSI Perspective
NSI holds historical trauma as legitimate biology and legitimate history — not political abstraction.
Clinical Implications
Effective care with affected communities honors these histories.
Practical Application
What happened to your people did not stop happening to your body when the events ended. That is real.
