The Wounded Knee massacre was a tragic event that occurred on December 29, 1890, on the Lakota Pine Ridge Indian Reservation in South Dakota. It was the result of rising tensions between the Native American Lakota people and the United States government, as well as the Ghost Dance movement, which was seen as a threat by the authorities. The U.S. Army surrounded a group of Lakota people, who were mostly unarmed, and a scuffle broke out, leading to the soldiers opening fire on the Native Americans. As a result, approximately 150-300 Lakota men, women, and children were killed, making it one of the deadliest attacks on Native Americans by the U.S. government. The Wounded Knee massacre is a significant event in American history as it marked the end of the Indian Wars and the final major confrontation between the U.S. Army and Native American tribes. It also highlighted the mistreatment and violence towards Native Americans and sparked further activism and advocacy for their rights and recognition.
