MINNEAPOLIS (AP) — A noose that was used in the largest mass execution in U.S. history will be returned to a Dakota tribe, the Minnesota Historical Society announced.

The society plans to repatriate what is known as the Mankato Hanging Rope to the Prairie Island Indian Community after the 30-day notice period required under federal law. It was used to hang Wicanhpi Wastedanpi — in English, Good Little Stars — also known as Chaske. He was one of 38 Dakota men executed in Mankato following the U.S.-Dakota War of 1862. It has been in the society’s collection since 1869, but out of sensitivity to the Dakota people, it is not on public display.

“This is a harmful and painful object that does not reflect the mission and the values of MNHS today,” the society said in a statement Tuesday.

The society said all 11 of the other federally recognized Dakota tribal nations have expressed support for the Prairie Island community’s claim, which was made under the Native American Graves Protection and Repatriation Act. The federal law sets up a process for museums and federal agencies to return certain Native American cultural items, including funerary and sacred objects, to tribes and direct decedents of the people they belonged to.
