This week marks 50 years since the start of the American Indian Movement’s 71-day occupation of the village of Wounded Knee on the Pine Ridge Indian Reservation. The occupation helped draw international attention to the plight of Indigenous peoples within the borders of the United States. The U.S. government responded to the occupation with a full military siege that included armored personnel carriers, F-4 Phantom jets, U.S. Marshals, FBI, state and local law enforcement. During the occupation, two Sioux men were shot dead by federal agents, and a Black civil rights activist, Ray Robinson, went missing. The FBI confirmed in 2014 that he had been killed during the standoff.
