Answer:
Ghost Dance
Explanation:
Ghost Dance refers to the religious movement started by Wovoka, which has spread across the Native American people in the West in the late nineteenth century. According to Wovoka, a new age would begin in 1891. He professed that dead people would return to life and the white folks would fade and give up ravaging the native population. While for Native Americans it was a traditional affair, a number of newspapers at that time linked ghost dance to suspected plots against white settlers.
