12. In 1890 Came the Wounded Knee Massacre
Wounded Knee was a site on a Lakota reservation in the Plains. The US military was disturbed by the burgeoning ghost dance movement that many natives had adopted. They arrested the chief, Sitting Bull, whom they mistakenly believed to be a ghost dancer, increasing tensions. When a shot was fired, a massacre broke out, and 150 (but possibly as many as 300) natives were killed with half of them being women and children.
