Final answer:
The massacre of Ghost Dancers at Wounded Knee in 1890 brought the Plains Indians wars to a close. This event marked the final act of physical resistance by Native Americans against the loss of their lands. The indiscriminate firing by US soldiers led to the deaths of many Lakota men, women, and children.
Step-by-step explanation:
The massacre of Ghost Dancers that brought the Plains Indians wars to a close is an important event in US History. It occurred in 1890 at the Wounded Knee Massacre in South Dakota. The Ghost Dance was a religious movement among the Lakota people, which led to concerns among White settlers of another uprising. When a group of Lakota Ghost Dancers tried to flee, the 7th Cavalry caught up to them and a rifle discharge triggered the US soldiers to open fire indiscriminately, resulting in the killing of approximately 150-300 Lakota men, women, and children. This marked the end of the Indian Wars, a series of conflicts between Native Americans and the US government over land and resources.
