What Native American leader was killed at wounded knee?

The Native American leader killed at Wounded Knee was Sitting Bull, a prominent chief of the Hunkpapa Lakota Sioux. However, it is important to note that he was killed in a separate incident in December 1890, prior to the Wounded Knee Massacre, which occurred later that month. The Wounded Knee Massacre involved the deaths of many Lakota Sioux, primarily women and children, during a confrontation with U.S. troops. The event marked a significant and tragic point in the history of Native American relations with the United States government.
