How did the Americans and the Indians react to the sand creek massacre and the wounded knee massacre?

The Sand Creek Massacre in 1864 elicited outrage among many Americans, particularly those opposed to the violence against Native Americans, leading to increased scrutiny of U.S. military actions. Conversely, the Wounded Knee Massacre in 1890 was met with a mix of Horror and indifference; some Americans condemned the brutality, while others viewed it as a justified end to Native resistance. For Native Americans, both events deepened feelings of betrayal and loss, solidifying resistance against U.S. expansion and exacerbating the trauma within their communities. These massacres became pivotal in shaping perceptions of U.S. policies towards Native Americans and fueled ongoing struggles for rights and recognition.
