Drumming and chanting filled the air as about 300 people gathered along the Minnesota-South Dakota border Friday to mark the 150th anniversary of the start of the US-Dakota War. The event was a symbolic welcoming home of the Dakota people exiled from the state following the conflict. Eight Dakota grandmothers, four on each side of the state border, exchanged eagle feathers and sage. Around 600 settlers and soldiers were killed in the six-week war in 1862. Many Dakota were starving at that time because of delayed annuity payments and unfilled treaty provisions, and a few hundred attacked to reclaim their longtime homeland. It ended in December with the largest mass execution in US history when 38 Dakota men were hanged in Mankato.
