Native American nations on the plains in the west continued armed conflicts with the U.S. throughout the 19th century, through what were called generally Indian Wars. Notable conflicts in this period include the Dakota War, Great Sioux War, Snake War and Colorado War. In the years leading up to the Wounded Knee massacre the U.S. government had continued to seize Lakota lands. A Ghost Dance ritual on the Northern Lakota reservation at Wounded Knee, South Dakota, led to the U.S. Army's attempt to subdue the Lakota. The dance was part of a religion founded by Wovoka that told of the return of the Messiah to relieve the suffering of Native Americans and promised that if they would live righteous lives and perform the Ghost Dance properly, the European American invaders would vanish, the bison would return, and the living and the dead would be reunited in an Edenic world. On December 29, 1890, at Wounded Knee, gunfire erupted, and U.S. soldiers killed up to 300 Indians, mostly old men, women and children.
