The U.S. army feared that the angry Ghost Dancers would soon start a rebellion with other tribes. When South Dakota settlers became disturbed by the Ghost Dancing, the U.S. army came to stop it and prevent it from spreading.
Since the Indians were losing land and buffalo were quickly disappearing, the Indians were angered by the whites. Eventually, a holy man named Wovoka saw a vision from the gods saying that order would soon be restored to Indian life. The Natives began doing tribal dances called "Ghost Dances" to please the gods, in hopes that they would restore order.
