Historical trauma occurs when trauma caused by historical oppression is passed down through generations. For more than 100 years, the Canadian government supported residential school programs that isolated Indigenous children from their families and communities (see Residential Schools in Canada). Under the guise of educating and preparing Indigenous children for their participation in Canadian society, the federal government and other administrators of the residential school system committed what has since been described as an act of cultural genocide. As generations of students left these institutions, they returned to their home communities without the knowledge, skills or tools to cope in either world. The impacts of their institutionalization in residential school continue to be felt by subsequent generations. This is called intergenerational trauma.
