What are the sand creek massacre and battle at wounded knee examples of us policy?

The Sand Creek Massacre and the Battle at Wounded Knee are stark examples of U.S. policy toward Native Americans during the 19th century, reflecting a pattern of violent repression and forced removal. The Sand Creek Massacre in 1864 involved the brutal killing of Cheyenne and Arapaho people by U.S. troops, demonstrating the government's willingness to use military force against Indigenous populations. The Battle at Wounded Knee in 1890 marked the tragic end of the Indian Wars, where U.S. troops killed hundreds of Lakota Sioux, illustrating the culmination of policies aimed at the assimilation and eradication of Native cultures. Both events highlight the systemic violence and disregard for Indigenous rights inherent in U.S. expansionist policies.
