Referring to the Wounded Knee Massacre of 1890, in which U.S. troops murdered Lakota Sioux Chief Sitting Bull and surrounded the Lakota camp. When one Lakota man refused to disarm, U.S. soldiers began firing, killing 300 Native Americans. While far from the deadliest attack, the Wounded Knee Massacre is emblematic of the U.S. government’s continued legacy of hostility towards and violence against Native American people (“Wounded Knee Massacre,” Encyclopaedia Britannica).
