What attracted the settlers west?
The Battle of Wounded Knee
The Battle of Wounded Knee occurred in 1890 at Wounded Knee, South Dakota. This attack on native Americans by the U.S. military was brought upon after the military had witnessed a religious ritual know as the "Ghost Dance." The military mistook it for a call to war. 150 unarmed natives were killed.
The Sand Creek Massacre
The Sand Creek Massacre occurred because some Native Americans attempted to rebel against white settlers instead of giving up their land. A small group of Cheyenne Indian ran an attack on some white settlers. They retaliated by killing 270 million Native Americans at Sand Creek, Colorado.
