This religion spread to many tribes on reservations in the West, including the Shoshone, Arapaho, Cheyenne, and Sioux (Dakota, Lakota, and Nakota). In fact, some bands of Lakota and Dakota were so desperate for hope during this period of forced relocation and genocide that, after making a pilgrimage to the Nevada Ghost Dance in 1889–1890, they became more militant in their resistance to the white colonists. Each Nation that adopted the Ghost Dance way provided their own understanding to the ceremony, which included the prediction that the white people would disappear, die, or be driven back across the sea. A Ghost Dance gathering at Wounded Knee in December 1890 was invaded by the Seventh Cavalry, who massacred unarmed Lakota and Dakota people, primarily women, children and the elderly.
