Her grandfather was so distraught over being forced to attend a Catholic boarding school for Indigenous children that even years later he would not step into a Catholic church.
But Christine Diindiisi McCleave never really learned what happened to him there — a common story among Native Americans trying to understand ancestral histories shadowed by trauma and cultural devastation.
"The U.S. and the churches have never been held accountable for this genocide," she told hundreds of Indigenous people gathered recently in south Minneapolis to honor boarding school survivors.
Recent findings of hundreds of unmarked graves near Canadian boarding schools for Natives, following the work of Canada's Truth and Reconciliation Commission, has spurred hope for Diindiisi McCleave and other advocates that a similar reckoning will come to the United States.
She could play an important role as leader of the National Native American Boarding School Healing Coalition (NABS), a nonprofit in Minneapolis formed a decade ago after a gathering of leaders from both countries discussed the need for a truth and reconciliation process in the U.S.
The coalition was charged with increasing public knowledge and healing regarding the forcible removal of Native children from their homes to attend government and church-run boarding schools so they could "assimilate" into white society, a policy from 1869 until nearly a century later.
Students often encountered abuse. They were forbidden to speak their language and practice their religious and cultural traditions, and some were never brought home.
Diindiisi McCleave was appointed the first CEO of NABS in 2015 and for several years was its sole employee. Investigating decades-old information about 367 American boarding schools proved arduous, and the coalition grew slowly. It filed Freedom of Information Act requests with the Bureau of Indian Affairs for details on the boarding schools, but the agency countered that it didn't do research — so NABS had to compile data of its own.
