C) the Ghost Dance

The Wounded Knee Massacre took place on December 29, 1890 in South Dakota. The U. S. troops had been uneasy about a dance called the "Ghost Dance" that had become popular among the indigenous people. They believed it could be a sign of insurrection. On December 19, the troops went in to disarm the Lakota while a dance was taking place. A deaf tribesman named Black Coyote accidentally fired his gun when resisting disarmament, and the U. S. Army began shooting at the Native Americans. When the massacre was over, more than 150-300 Lakota were dead, and 51 were wounded (some of which died later).
