What is Generational Trauma?
Generational trauma — also referred to as intergenerational or transgenerational trauma — refers to the repetition of traumatic experiences passed down from ancestors to descendants. It manifests in emotional, behavioral, and even psychological ways. The triggering factors can either be personal, such as traumatized parents projecting their pain onto children, or collective, like racism, violence, oppression, and tragedy.
Scientific Insights
Research on Holocaust survivors revealed that trauma affected not only their mental state but also stress responses, potentially altering genetic makeup. Even after resettling post–World War II, their stress levels remained high, putting subsequent generations at risk. Studies beginning in the 1970s showed that while children of survivors did not display significantly higher psychopathology than others, they exhibited greater susceptibility to PTSD, difficulties with individuality, and a complex mix of resilience and vulnerability when facing stress.
Global Examples of Inherited Trauma
Afghans have endured over forty years of continuous conflict, beginning with the Soviet invasion in 1979, followed by civil war, the rise of the Taliban, and prolonged instability. Cycles of violence forced millions into refugee camps in Pakistan, Iran, and beyond. A 2018 EU survey found that 85% of Afghans had witnessed at least one traumatic event.
The impact of historical traumas also extends to colonization, slavery, and forced displacement. First Nations and American Indian communities, African Americans, Australian Aboriginals, Palestinians, Cambodians, Armenians, and people from former Yugoslavia all carry inherited scars of genocide, ethnic cleansing, and war.
One striking example is the Tulsa Massacre of 1921, when “Black Wall Street,” a thriving African American community, was destroyed by white mobs. Homes and businesses were burned, survivors lost property, insurance claims were denied, and perpetrators went unpunished. The silence that followed deepened psychological wounds for generations.
Contributing Factors Beyond History
Trauma is rarely a single event—it is often continuous, destabilizing identity, trust, and well-being.
Healing and Moving Forward
Generational trauma reminds us that the past does not always stay in the past—it echoes into the present. From the racial violence in Tulsa to Afghanistan’s decades-long war, inherited pain continues to shape lives.
Yet, alongside pain come survival and resilience. Healing requires:
By combining personal healing with systemic change, future generations can break cycles of trauma and transform inherited pain into resilience and growth
