African American poetry often explores how slavery, racial violence, displacement, exclusion, and systemic injustice continue to affect descendants long after original events. The concept helps explain recurring motifs of inherited fear, silence, fragmented memory, bodily anxiety, and ancestral grief. Poets use such themes to show that historical violence is not confined to the past but remains embedded in identity, family narratives, and communal consciousness.

Intergenerational trauma, as a concept applied to African American communities, refers to the ways in which unresolved historical traumas — slavery, lynching, segregation, mass incarceration — are transmitted psychologically, culturally, and potentially epigenetically across generations. In poetry, intergenerational trauma manifests as the haunting of the present by the past, the re-enactment of historical wounds in contemporary relationships, and the inheritance of both suffering and survival strategies. Lucille Clifton's poetry, which frequently moves between her own life and her ancestors' experiences, is exemplary. Students should engage with Marianne Hirsch's concept of "postmemory" alongside Black-specific theorisations. Related terms include enslavement memory, grief work, historical memory, countermemory, and survival poetics.
