1890-Sitting Bull has been arrested and killed by army troops at his lodge just south of the border between North and South Dakota. Alarmed federal officals had ordered the arrest of the Sioux cheif for encouraging what they call the ‘Ghost Dance Craze.’ Many Indians across the West, particular the Sioux, have been obsessed with this religious dance, which they believe will rid them of the white man, bring back the buffalo, and restore their old way of life. In response to the killing of Sitting Bull, and fearing for their own lives, hundreds of Sioux flee their reservations and Indian agencies in South Dakota.
