The Wounded Knee Massacre occurred on December 29, 1890, when U.S. Army troops confronted a group of Lakota Sioux near Wounded Knee Creek in South Dakota. The confrontation began as an attempt to disarm the Native Americans, but tensions escalated, leading to gunfire. In the chaos, approximately 300 Lakota men, women, and children were killed, making it one of the last major conflicts between the U.S. government and Native American tribes. The massacre marked a significant and tragic event in the history of U.S.-Native American relations, symbolizing the violent suppression of Indigenous cultures.
