The Associated Press: The federal government will investigate its past oversight of Native American boarding schools and work to “uncover the truth about the loss of human life and the lasting consequences” of policies that over the decades forced hundreds of thousands of children from their families and communities, U.S. Interior Secretary Deb Haaland announced Tuesday.

The unprecedented work will include compiling and reviewing records to identify past boarding schools, locate known and possible burial sites at or near those schools, and uncover the names and tribal affiliations of students, she said.

“To address the intergenerational impact of Indian boarding schools and to promote spiritual and emotional healing in our communities, we must shed light on the unspoken traumas of the past no matter how hard it will be,” Haaland said.

Haaland outlined the initiative while addressing members of the National Congress of American Indians during the group’s midyear conference.

She said the process will be long, difficult, and painful and will not undo the heartbreak and loss endured by many families.

Starting with the Indian Civilization Act of 1819, the U.S. enacted laws and policies to establish and support Indian boarding schools across the nation. For over 150 years, Indigenous children were taken from their communities and forced into boarding schools that focused on assimilation.

Haaland talked about the federal government’s attempt to wipe out tribal identity, language, and culture and how that past has continued to manifest itself through long-standing trauma, cycles of violence and abuse, premature deaths, mental health issues, and substance abuse.

The recent discovery of children’s remains buried at the site of what was once Canada’s largest Indigenous residential school has magnified interest in the troubling legacy both in Canada and the United States.

In Canada, more than 150,000 First Nations children were required to attend state-funded Christian schools as part of a program to assimilate them into society. They were forced to convert to Christianity and were not allowed to speak their languages. Many were beaten and verbally abused, and up to 6,000 are said to have died.
