What was the role of buffalo soilders?

Buffalo Soldiers were African American soldiers who served in the U.S. Army after the Civil War, primarily from 1866 to the 1890s. They were instrumental in various military campaigns, including the Indian Wars, and played a key role in the westward expansion of the United States. The nickname "Buffalo Soldiers" is believed to have originated from Native Americans who admired their bravery and saw similarities between the soldiers' hair and that of buffalo. Despite facing racial discrimination, they contributed significantly to the military and helped secure rights and opportunities for future generations.
