Wounded Knee Massacre (Day of Reflection)

Wounded Knee Massacre, (December 29, 1890), the slaughter of approximately 150–300 Lakota Indians by United States Army troops in the area of Wounded Knee Creek in southwestern South Dakota. The massacre was the climax of the U.S. Army’s late 19th-century efforts to repress the Plains Indians. It broke any organized resistance to reservation life and assimilation to white American culture, although American Indian activists renewed public attention to the massacre during a 1973 occupation of the site.
