"After the Ghost Dance spread across the Rockies to the Plains tribes it ran amok. ...The fervor attacked the Plains tribes virulently, particularly the Sioux, who were at that time the largest and the most intransigent of them all. The Sioux had been forced to submit to a series of land grabs and to indignities that are almost unbelievable when read about today. ...they were being systematically starved into submission—by the White Bureaucracy—on the little that was left of their reservation in South Dakota. ...From Rosebud, the Ghost Dance spread like prairie fire to the Pine Ridge Sioux and finally to Sitting Bull's people at Standing Rock. The Sioux rebelled; the result was the death of Sitting Bull and the massacre of the Indians (despite their ghost shirts) at Wounded Knee in 1890."
