Intergenerational trauma refers to the trauma that is passed from a trauma survivor to their descendent. Due to violent and terrifying events—such as war, ethnic cleansing, political conflict, environmental catastrophe, and more—experienced by previous generations, descendants may experience adverse emotional, physical, and psychological effects. As the original sources of trauma are structured by forms of discrimination such as race and gender, intergenerational trauma also occurs along intersectional axes of oppression. For example, Black communities have brought to light the intergenerational trauma of enslavement.
Intergenerational trauma is sometimes called historical trauma, multi- or transgenerational trauma, or secondary traumatization.
